Find the missing angle x
WebAn equilateral triangle is one in which all three angles are equal. The angles add up to 180°, so each angle is 60°. You don't need to be told any angles in an equilateral to find … WebFind the value of x. Solution: We can consider the wall to be a straight line. Then, x and the 15 ∘ angles are angles on a straight line. That means they are supplementary angles. So, x + 15 ∘ = 180 ∘ x = 180 ∘ – 15 ∘ x = 165 ∘ Frequently Asked Questions on Finding Unknown Angle Measures What are congruent angles?

Since we have 5x+40 = 90, in order to just have x on the left-hand side, we would need to get rid of the 5 and +40. First, +40. To get rid of it and make it 0, what do we need to do? Well, we need to subtract 40 since 40-40 = 0.
