What is the value of x in the triangle?
Answer:
D. 2√2
Step-by-step explanation:
sin 45° = 1/√2
P/H = 1/√2
x/4 = 1/√2
= 1/√2 × 4
= 4/√2
x = 4×√2/√2×√2
= 4√2 /2
= 2√2
Option D. 2√2
Solve the right triangle. Round decimal answers to the nearest tenth.
AB² = AC²+BC²
AB² = 9²+12²
AB²= 225
AB= 15
SinA = 12/15
A = Sin-¹(0.8)
M`A = 53°
M`B = 90- A = 90-53= 37°
Answer:
AB = 15
m ∠A = 53.1°
m ∠B = 36.9°
Step-by-step explanation:
[tex]AB^2 = AC^2+CB^2 \\AB^2 = 9^2 + 12^2 = 81 + 144 = 225\\AB = \sqrt{225} = 15[/tex]
[tex]sin A = \frac{opposite}{hypotenuse} = \frac{12}{15}\\\\A = sin^{-1} (\frac{12}{15})\\\\[/tex]
A = 53.13
m∠A = 53.1°
∠A + ∠B + ∠C = 180°
53.1 +∠B + 90 = 180
∠B = 180 - 90 - 53.1 = 36.9°

darren has a e bag of snack mix. Each serving is 1/4 cup. Which model will help him determin how many 1/4 cup servings are in the whole bag of snack mix?
Answer:
4e
Step-by-step explanation:
Since each serving is 1/4 cups
If the total number of snack mix in bag is e :
The number of 1/4 cups of serving in the bag can be obtained thus :
Total snack mix in bag / fraction of cup per serving
e / 1/4
e * 4/1
= 4e
Solve using the quadratic formula. Show all work. Write each solution in simplest form. No decimals.
Answer:
[tex]6+ \sqrt{29},6-\sqrt{29}[/tex]
Step-by-step explanation:
The given quadratic equation is [tex]x^2-12x+7=0[/tex]
The general form of quadratic equation is given by :
[tex]ax^2+bx+c=0[/tex]
Comparing both the equations,
a = 1, b = -12 and c = 1
The solution of a quadratic equation is given by :
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]
Put all the values,
[tex]a=\dfrac{-(-12)\pm \sqrt{(-12)^2-4\times 1\times 7} }{2(1)}\\\\=\dfrac{12\pm \sqrt{116}}{2}\\\\=\dfrac{12\pm 2\sqrt{29}}{2}\\\\=6\pm \sqrt{29}[/tex]
So, the solutions of the given equation is [tex]6+ \sqrt{29},6-\sqrt{29}[/tex]. Hence, the correct option is (d).
how much paper is needed to cover a rectangular bulliten board that is 29 in. wide and 37 in. high?
Answer:
1073 inches squared.
Step-by-step explanation:
To find how much paper is needed to cover the board, you have to find the area. The formula of area for rectangles is length times width or as you said in the question width times height.
To find the answer:
Area = length * width
Area = 29 * 37
Area = 1073 inches squared.

ITS MULTIPLE CHOICE PLS HELP Determine whether QR is tangent to the circle. Justify your answer.
Answer:
(A)
Step-by-step explanation:
The line QR is tangent at point R if it is perpendicular or makes a right angle to line PR. If so, then the Pythagorean theorem can be applied. And it turns out that indeed the aquarebof the length of line QP is equal to the sum of the squares of QR and PR.
how do i do tangent lines?
Answer:
x = 154°
Step-by-step explanation:
The 4 interior angles of the quadrilateral sum to 360°
The angles between the tangents and the radii = 90°
Then
x = 360° - (90 + 90 + 26)° = 360° - 206° = 154°
The following triangular prism has a volume of 10 cubic units and a height of 5 units. The triangular pyramid has a congruent base and the same height, and its longest edge is 7.5 units long. What is the volume of the pyramid?
Answer:
10/3 cubic units (proof below!)
Step-by-step explanation:
The volume of pyramid is, 10/3 cubic units
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Here, We have;
Volume of triangular prism = Base area x Height
= 10
And, Volume of triangular pyramid = 1/3 x Base area x Height
Since, The triangular pyramid has a congruent base and the same height.
Hence, The volume of pyramid = 1/3 x 10
= 10/3 cubic units
Thus, The volume of pyramid is, 10/3 cubic units
