The measure of two equal angles of an isosceles Triangle are 55° and 55° if the measure of third angle is 70°
Given:
To Find:
Concept to be used:
Step 1:
Assume that Measure of equal angles are a , a
Step 2:
Equate the sum of measure of 3 angles with 180°
a + a + 70° = 180°
Step 3:
Solve for a:
2a + 70° = 180°
=> 2a = 110°
=> a = 55°
Hence measure of two equal angle are 55° and 55°.
