Answer:
Step-by-step explanation:
<u>Given information</u>
∡ 1 = 90°
∡ 2 = 50°
∡ 3 = x°
Total Angle = 180° <em>(Triangle angle sum theorem)</em>
<u>Given formula</u>
∡ 1 + ∡ 2 + ∡ 3 = Total Angle
<u>Substitute values into the formula</u>
(90) + (50) + (x) = (180)
<u>Combine like terms</u>
140 + x = 180
<u>Subtract 140 on both sides</u>
140 + x - 140 = 180 - 140
Hope this helps!! :)
