- Corresponding Angles - Angles that are congruent to each other and occur with parallel lines
Step-by-step explanation:
<u>Step 1: Identify</u>
We see that the measures given are Corresponding Angles
<u>Step 2: Solve for </u><em><u>x</u></em>
- Set up equation: 8x - 7 = 9x - 28
- Subtract 8x on both sides: -7 = x - 28
- Add 28 on both sides: 21 = x
- Rewrite: x = 21
Answer:
a = 8
Step-by-step explanation:
-5(a + 3) = - 55
- 5a - 15 = - 55
55 - 15 = 5a
5a = 40
a = 40 : 5
a = 8
Answer:
X=22/5
Step-by-step explanation:
By cross multiplication
5/2 =11/x
5x = 2(11)
5x =22
X=22/5
