Since its a 45-45-90 triangle then the 2 legs are going to be the same.
Answer:
90°
Step-by-step explanation:
Always remember that the sum of all angles is 180°.
So there are two 45° angles, so just add them up and you get 90
So if you subtract 90 from 180, you get 90, and that's your answer

A right triangle has a hypotenuse that measures 10 mm and a leg, a, that measures 8 mm. What is the length of leg b?
Answer:
6mm
Step-by-step explanation:
pythagorean theorem
Answer:
Solution given:
length[a]=8mm
base(b)=xmm
hypotenuse [c]=10mm
we have
by using Pythagoras law
a²+b²=c²
8²+x²=10²
x²=100-64
x=√36
x=6mm
the length of the leg b is 6mm.

what is the answer to this equation:5x-4x+2=1
Answer:
[tex]x=-1[/tex]
Step-by-step explanation:
[tex]5x-4x+2=1[/tex]
Step 1: Simplify both sides of the equation.
[tex]5x-4x+2=1[/tex]
[tex]5x+-4x+2=1[/tex]
[tex](5x+-4x)+(2)=1[/tex] (Combine Like Terms)
[tex]x+2=1[/tex]
[tex]x+2=1[/tex]
Step 2: Subtract 2 from both sides.
[tex]x+2-2=1-2[/tex]
[tex]x=-1[/tex]
Therefore, [tex]x=-1[/tex] will be your final answer.
PLEASE HELP The diameter D of a sphere is 19 m. Calculate the sphere's surface area A.
Use the value 3.14 for at, and round your answer to the nearest tenth.
Answer:
A = 1,133.5 m³
Step-by-step explanation:
Surface area of a sphere, A = 4πr²
π = 3.14
Radius, r = diameter / 2
= 19 m / 2
= 9.5 m
Surface area of a sphere, A = 4πr²
A = 4 * 3.14 * (9.5)²
= 4 * 3.14 * 90.25
= 1,133.54
A = 1,133.54 m³
To the nearest tenth
A = 1,133.5 m³

Answer:
Martha needs 10 more days
Step-by-step explanation:
25 Liters = 5 days
25*2=50 so double equation
25*2=5*2
50 Liters =10 days
it takes 10 days to jar 50 Liters of jam
Michelle invests $1000 at a bank offering 3% compounded quarterly.
Answer:
A = 1000(1 + .03 /4)4t
Explanation:
The money invested is the principal that is $ 1000.
The quarterly interest = 3/4 = 0.75 %
Assuming the number of years the money invested was x, then the interest period (n) will be 4 x (quarters)
Using the formula, A = P (1 + r/100)∧n
Therefore, the growth of the investment will be given by
1000( 1.0075)∧n, where n is the interest period.

A cooler has 6 Dr Peppers, 5 Diet Cokes, 9 Cokes, and 4 Sprites in it.
What is the probability of Sam choosing a Dr Pepper, changing his mind and putting it back, and then choosing a Diet Coke instead?
NO LINKS
a
5/96
b
11/24
c
1/576
d
1/24
Answer:
A
Step-by-step explanation:
6/24 multiplied by 5/24
The probability of Sam choosing a Dr Pepper, changing his mind and putting it back, and then choosing a Diet Coke instead is 5/96.
The probability of Sam choosing a Dr Pepper on his first pick is 6/24 (since there are 6 Dr Peppers out of a total of 24 sodas).
After he puts it back, there are still 24 sodas in the cooler
since there are 5 Diet Cokes remaining out of a total of 24 sodas
so the probability of him choosing a Diet Coke on his second pick is 5/24
The first pick does not affect the second pick
we can multiply their probabilities to get the probability of both events happening together:
Probability of choosing a Dr Pepper and then a Diet Coke
= (6/24) × (5/24)
= 5/96

What is the relationship between the number of sides of the base of a prism and the number of lateral faces? The number of sides of the base of a prism is less than the number of lateral faces. The number of sides of the base of a prism and the number of lateral faces is equal. The number of sides of the base of a prism is greater than the number of lateral faces. There is no consistent relationship between the number of sides of the base of a prism and the number of lateral faces.
Answer:
Every prism has as many faces, and edges, as its base has sides. Thus, a prism with an octagonal (eight sided) base has eight lateral faces, and eight lateral edges. Each lateral face meets two other lateral faces, as well as the two bases. As a consequence, each lateral face is a four sided polygon.
The number of sides of the base of a prism and the number of lateral faces is equal.
What is a prism?A prism is a three-dimensional object with two congruent and parallel faces, called the bases and it encloses the space between the bases. Every cross-section parallel to the base of a prism is congruent to its base.
How do we solve the given question?In the question, we are asked to tell the relationship between the number of sides of the base of a prism and the number of lateral faces.
We let the number of sides of the base of the prism be s, and let the number of lateral faces of the prism be f.
We know that a prism has two parallel and congruent bases and every corresponding side of the base are connected by a pane. These planes are the lateral faces of the prisms. As each corresponding pair of sides is connected by one lateral face, the number of the lateral face is equal to the number of sides of the base.
∴ The number of sides of the base = The number of lateral faces of the prism
or, s = f.
∴ We can say that the number of sides of the base of a prism and the number of lateral faces are equal.

Answer:
The solution of this trigonometric identity is [tex]\theta = 56.310^{\circ} \pm 180\cdot i ^{\circ}[/tex], [tex]\forall \,i\in \mathbb{N}_{O}[/tex].
Step-by-step explanation:
Let [tex]7\cdot \tan \theta - 8 = 5\cdot \tan \theta -5[/tex], we proceed to simplify the expression and solve afterwards either by algebraic or by trigonometric means:
[tex]7\cdot \tan \theta -8 = 5\cdot \tan \theta -5[/tex]
[tex]2\cdot \tan \theta = 3[/tex]
[tex]\tan \theta = \frac{3}{2}[/tex]
[tex]\theta = \tan^{-1} \frac{3}{2}[/tex]
The tangent is a trigonometric function with a period of 180°. Hence, we find that the family of angles associated with such value is:
[tex]\theta = 56.310^{\circ} \pm 180\cdot i ^{\circ}[/tex], [tex]\forall \,i\in \mathbb{N}_{O}[/tex]

Answer:
1. measure of angle E is 90 degrees
2. Measure of angle F + measure of angle G is 90 degrees
Step-by-step explanation:
Angle E is 90 degrees because it is marked as a right angle (the square)
A triangle has 180 degrees so if E is 90 degrees then the other 2 also have to equal 90 degrees
The polygons in each pair are similar. Find the scale factor of the smaller figure to the larger figure

Answer:
(3) z = 99°
(4) thirty thousand, six hundred and eighty-two
Step-by-step explanation:
(3) From the diagram,
Since the triangle is an issoceles triangle, The angle of the base are equal.
Applying
180° = x+x+18 (sum of angle in a triangle)
Where x = angle of each base of the triangle
180° = 2x+18
2x = 180-18
2x = 162
x = 162/2
x = 81°
But
x+z = 180 (sum of the angle in a straight line)
z = 180-x
z = 180-81
z = 99°
(4) 30682 in words = thirty thousand, six hundred and eighty-two
