Answer:
<h2>x = 35</h2>
Step-by-step explanation:
Because the angles are vertical angles, they must be equal.
3x + 7 = 112
3x = 105
x = 35
Check
3(35) + 7 = 112
112 = 112 Correct
.1125 = 11.25% or 11 1/4(fraction)
Answer:
W = 69.5 L = 109.5
Step-by-step explanation:
L = 3W-99
Perimeter = 2L + 2W
358 = 2(3W-99) + 2W
358 = 6W-198 + 2W
358 = 8W-198
556 = 8W
69.5 = W
- 358 = 2L+2W
- 358 = 2L + 2(69.5)
- 358 = 2L + 139
- 219 = 2L
- L = 109.5
Answer:
Step-by-step explanation:
all i know is its 11 degrees warmer
X^2 + 6^2 = {sqrt (117)}^2
x^2 + 36 = 117
Solve for x.
x^2 = 81
x = 9
