Answer:
angle A is 94
angle B is 86
Step-by-step explanation:
supplementary angles add up to 180°
(6x + 10) + (4x + 30) = 180
10x + 40 = 180
10x = 140
x = 14
A is 94
B is 86
The answer: The absolute value

Let the width be x, then length = 24 +x
Perimeter = 2(length + width)
2(x + 24 + x) = 172
2(2x + 24) = 172
4x - 48 = 172
4x = 172 + 48 = 220
x = 220/4 = 55
Therefore, width is 55 and length is 55 + 24 = 79
Answer:4x + 2 = -18 slove for what is x
