Answer:
x= 6 and b= 126°
Step-by-step explanation:
okay the first step to solving this is understanding what are the properties of ∠A and ∠B.
so the angles are equal to each other because they are alternate interior angles.
if that is settled it means the equation for both angles would be equal to each other as well.
∠A= 8x + 78° ∠B= 2x + 114°
therefore: 8x + 78= 2x + 114
then solve for x:
- isolate x and the answer is equal to 6 at the end
now you are looking for angle b, so you input x which is 6 into the equation;
= 2(6) + 114°
=12 + 114°
=126°
Answer:
40%
Step-by-step explanation:
You can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 6 and 15 using
GCF(6,15) = 3
6÷315÷3=25
We know that
25
is the same as
2÷5
Then using
Long Division for 2 divided by 5
gives us
0.4
Converting our number to a percentage:
0.4×100
=40%
Answer:
7a+1 +9 × 7a÷7a+2- 45 ×7a
7a+1 +9 × 1+2-45 ×7a
7a+1 +9 + 2-315a
7a+12-315a
12-308a
4(3-77a)
Answer:
Step-by-step explanation:
Use the volume formula of a right rectangular prism!
V=whl
Just plug the values in and throw them in your calculator.
w stands for width
h stands for height
l stands for length
Hope that helps. Since it is part of a quiz, I can't give you the answer, but I believe in you!
