Question

Two of the angles of a triangle are equal and the third angle is 70 degree .fi d the measure of the unknown angle .please example it​

Answer 1

Answer:

base angle=55°

Step-by-step explanation:

2*base angles=180-70

base angle=110/2=55°

Answer 2

Okay, so here there are two unknown angles. Let each of the unknown angles be "x".

GIVEN: Two angles are equal, 3rd angle = 70⁰

In a triangle, all the angles sum up to 180⁰. This is called Angle Sum Property.

--> x + x + 70⁰ = 180⁰ [A.S.P]

--> 2x = 180⁰ - 70⁰

--> x = 110/2

--> x = 55⁰

∴ Measure of unknown angles are 55⁰ each
