What are the measures of ∠1 and ∠2? PLEASE ANSWER
m∠1 = 58.2°, m∠2 = 75.5°
m∠1 = 67.4°, m∠2 = 104.5°
m∠1 = 75.5°, m∠2 = 67.4°
m∠1 = 104.5°, m∠2 = 58.2°
9514 1404 393
Answer:
(b) m∠1 = 67.4°, m∠2 = 104.5°
Step-by-step explanation:
It is easiest to find angle 2 first, then make your answer selection based on that.
The exterior angle 121.8° is the sum of the remote interior angles 17.3° and angle 2. Then ...
angle 2 = 121.8° -17.3° = 104.5° . . . . . . . matches the second choice
__
Angle 2 is an exterior angle of the top triangle. It, too, is the sum of the remote interior angles:
104.5° = angle 1 + 37.1°
angle 1 = 104.5° -37.1° = 67.4°
Answer:
C!
Step-by-step explanation:
m∠1 = 75.5°, m∠2 = 67.4°

A farmer sells 8.3 kilograms of apples and pears at the farmer's market. 1/4 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?
Answer:
6.23 kg of pears (check for rounding)
Step-by-step explanation:
8.3 / 4 = 2.08 kg of apples as it is 1/4 of 8.3
8.3 - 2.08 = 6.22 kg of pears
the measures of the angles of a triangle are shown in the figure below. solve for x
Answer:
the the figure shown x=7
Answer:
7°
Step-by-step explanation:
7x + 5 °+ 36° + 90 °= 180° ( being sum of angles of triangle )
7x + 131° = 180°
7x = 180 °- 131 °
7x = 49°
x = 49° / 7
x = 7°

CDE is a straight line.
(a) Work out angle BDE
Give a reason for your answer.
(b) Work out angle CDB
Give a reason for your answer.
Answer:
a) ∠BDE is 60° because ΔBDE is an equilateral triangle with all three angles = 60°.
b) ∠CDB = 120° because 180° - 60° = 120°

Find the value of k that makes the function continuous
Answer:
13/3
OR
4.33333
Step-by-step explanation:
For this function to be continuous, the second function must have the value of the limit as x approaches 3 of the first function.
To find [tex]\lim_{x \to 3} \frac{2x^2-3-15}{x-3}[/tex] we have to factor the top of the fraction
2x^2 - 3 -15
2x^2 - 18
2* (x^2 - 9)
2 * (x + 3) (x - 3)
this is perfect because this cancels out the x - 3 on the bottom
so the function become f(x) = 2 * (x + 3)
When 3 is plugged in it becomes 2 * (3 + 3) = 2 * 6 = 12
Now if you plug in 3 to the second function and make it equal to 12, you can find the value of k.
k*(3) - 1 = 12
k*3 = 13
k = 13/3
k = 4.33

The product of the expression (3x² - 2) (4x² + 5x) is 12x⁴ + 15x³ - 8x² - 10x.
What is Multiplication?
Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Given expression is (3x² - 2) (4x² + 5x).
This can be written as,
(3x² - 2) (4x² + 5x) = 3x² (4x² + 5x) - 2 (4x² + 5x)
We have to use distributive property here.
a(b + c) = ab + ac for any three numbers or expressions, a, b and c.
(3x² - 2) (4x² + 5x) = 3x² (4x² + 5x) - 2 (4x² + 5x)
= (12x⁴ + 15x³) - (8x² + 10x)
= 12x⁴ + 15x³ - 8x² - 10x
Hence the product is 12x⁴ + 15x³ - 8x² - 10x.

Which statement is not true about the pattern shown?
2/3 4/6 8/12 16/24
A-Each fraction is greater than the previous fraction.
B-Each fraction is equal to the previous fraction in the pattern multiplied by
C-Each fraction is equivalent to 2/3
D-The next fraction in the pattern is 32/48
Answer:
The answer is A-Each fraction is greater than the previous fraction.
Step-by-step explanation:
To prove that A is wrong, first simply all fractions.
2/3 is already simplified.
4/6 can reduce to 2/3, which already proves that A is wrong.
So, because 2/3 and 4/6 are equal fractions, and A says that each fraction is greater than the previous one, A is wrong.

Find the value of x 116 degrees and 33 degrees
Answer:
x = 31 degrees
Step-by-step explanation:
This is a triangle because there are 3 angles so they all add up to 180 degrees.
116 + 33 + x + 180 Add 116 and 33
149 + x = 180 subtract both sides by 149
x = 31
