Question

one of the angles is equal to the sum of other two . find the measure of this angle.

Answer 1

Answer:

angle = 90°.

Step-by-step explanation:

Let the Angles of the triangle be A , B and C respectively.

Let A =  B + C

we know that A + B + C = 180°

Hence,    A + A = 180°

  A = 90°

The largest angle in the triangle is 90°.

Answer 2

hey if it is a triangle then
let the angles be /_A, /_B, /_C
angleA=angleB+ angle C
As we know angleA+angleB+ angleC=180 degree (angle sum property)
angleB+angleC=180 - angleA
put this in value of angleA
angleA=180 - angle A
angle A+ angle A=180 degree
2(angleA)=180 degree
angle A= 180/2=90 degree.
