WebAug 14, 2024 · Use a protractor to measure the three angles. Use your measurements to conjecture about the value of a + b + c. Find the exact value of a + b + c by reasoning about the diagram. Summary To find an unknown angle measure, sometimes it is helpful to write and solve an equation that represents the situation. WebFind the measure of the missing angles x and y in the diagram below. Solution x = 80 o (the exterior angle = the opposite interior angle). y + 70 o = 180 o (opposite angles are supplementary). Subtract 70 o on both sides. y = 110 o Therefore, the measure of angles x and y are 80 o and 110 o, respectively. Example 2 ctcl disease
