Step-by-step explanation:
Answer: 2?
Step-by-step explanation:
10 × (6 + 8) = 10 × 14 = 140
Answer:
<h2><em><u>
1. x = 36 is the answer.</u></em></h2><h2><em><u>
2. x = 123 is the answer.</u></em></h2>
Step-by-step explanation:
1. 4x = angle 4
x = angle 1
Angle 1 + angle 4 = 180
4x + x = 180
5x = 180
<h2><em><u>
x = 36.</u></em></h2>
<em><u></u></em>
2. 55 = angle 2
angle 1 = 68
angle 3 = 55 + 68 = 123 = 180 - 123 = 57
Angle 4 = 57
<h2>180 - 57 = 123</h2><h2><em><u>
x = 123</u></em></h2><h2><em><u>
</u></em></h2>
