Question

9. Find the measure of each of the two equur
triangle are of the same measure, find the measure of each oth​

Answer 1

Answer:

Step-by-step explanation:

Given that the isoceles triangle is right - angled .

so , one of the angle is 90 and the the other two are equal ,

then let the equal angles be 2 x = ( x + x )

A/q , 90 + 2 x = 180

=> 2x = 90

=> x = 45

hence, the equal angles are 45 .

given all the angles are equal so ,

let them be x + x + x = 3 x

now , 3 x = 180

=> x = 60 .

hence , each angle measures 60 .

now don't be selfish and  mark my answer as brainliest.
