Question

Two angles of a triangle measure 12 and 40. What is the measure of the third triangle?

Answer 1

Step-by-step explanation:

let measure of 3rd angle be x

12+40+x=180

52+x=180

x=180-52

x=128

Answer 2

$\bf\underline{\underline{\red{SOLUTION:-}}}$

Question

• Two angles of a triangle measure 12 and 40. What is the measure of the third triangle?

Answer

• Measure of third angle be 128°

Given

• Two angles are 12 and 40

To Calculate

• Measure of third angle?

Explanation

Two angles are 12 and 40

Let third angle be x

☆ Sum of all angles of triangle = 180

➥ 12+40+x=180

➥ 52 +x=180

➥ x=180-52

➥ x= 128

$\bf\underline{\underline{\red{HENCE:-}}}$

• Measure of third angle be 128°
