Question

In a triangle, the sum of the interior angles is 180o. Find the measure of angle x, if angle y = 43o and angle z = 67o.

A. Write the algebraic equation using the information above. (5 points)

B. Solve the equation. Show all work. (10 points)

C. What is the measure of angle x? Make sure to label your answer. (5 points)

Answer 1

Is this answer correct?

A. Angle y + Angle z + Angle x = 180o
Angle y = 43o
Angle z = 67o
Angle x = X
B.
43 + 67 + x = 180
110 + x = 180
110 - 110 + x = 180 - 110
x = 70
43 + 67 + 70 = 180
C.
The measure of Angle x is 70 degrees.
