Use the relationship between the angles in the figure to answer the question. Which equation can be used to find the value of x? x + 90 = 61 x + 90 + 61 = 180 x + 61+ 90 = 90 x + 61 = 180 Three line making six angles with the leftmost angle at sixty one degrees the top right angle labeled with a square to indicate a right angle and the bottom middle angle labeled X degrees
Accepted Solution
A:
x+90+61=180 ( the sum of the three angles in a triangle is 180 °)
