Question

one angle of a triangle is 40 degree and other two angle are equal. what will be the measure of each if these angles. ​

Answer 1

$let \: the \: other \: 2 \: angles \: be \: x \\ angel \: 1 = 40 \\ 40 + x + x = 180 \\ 2x = 180 - 40 \\ 2x = 140 \\ x = \frac{140}{2} \\ x = 70$

Answer 2

Answer:

Step-by-step explanation:

Let the second and third angle be x

Sum of all the angles of a triangle=180∘

40∘+ x+x= 180∘

40∘+2x=180∘

2x=180∘– 40∘

2x=140∘

x=70

THEREFORE SECOND AND THIRD ANGLE ARE 70 DEGREES EACH
