Smaller angle = 41°
Larger angle = 139°
Step-by-step explanation:
(7x - 1) + (2x + 1) = 180
7x + 2x - 1 + 1 = 180
9x = 180
x = 20
- The measure of the smaller angle is
2x + 1
= 2(20) + 1
= 40 + 1
<u>= 41°</u>
- The measure of the larger angle is
7x - 1
= 7(20) - 1
= 140 - 1
<u>= 139°</u>

I think the number would be 1.
Start from the last equation:
2w = 8 ⇒ w = 4
z = w + 1 ⇒ z = 4 + 1 ⇒ z = 5
y = 2z - 3w ⇒ y = 2•5 - 3•4 ⇒ y = -2
3x + 2y - z + 5w = 20 ⇒ 3x + 2•(-2) - 5 + 5•4 = 20
⇒ 3x = 9 ⇒ x = 3
