The sum of the measures of the angles of all triangles is 180 degrees. If one angle of the triangle measure 45 degrees. The meas
ure of the other two angles is equal. What is the measure of the other two angles? Write an equation and solve
2 answers:
180-45=135
135/2=67.5 for the other two angles
Answer:
67.5 degrees.
Step-by-step explanation:
Let the measure of two equal angles of the triangles is x.
Thus, the angles of the triangles are x, x and 45 degrees.
The sum of the measures of the angles of all triangles is 180 degrees.
Hence, the equation is
x + x + 45 = 180
Solve the equation for x
2x + 45 = 180
2x = 180 - 45
2x = 135
x = 67.5
Therefore, measure of other two angles are 67.5 degrees.
