Question

if the measure of two angles of a triangle is 47 and 52 respectively then find the measure of third angle. (with method)​

Answer 1

Step-by-step explanation:

let the a=47,b=52,c=?

measurement of all angles of triangle =180

a+b+c=180

47+52+x=180

x=180-99

x=81

measure of third angle is 81

Answer 2

Given

Angle 1 of Triangle ⇒ 47

Angle 2 of Triangle ⇒ 52

______________________________________

To Find

Third Angle of the triangle.

______________________________________

Solution

All angles in a triangle always sums upto 180°.

Angle 1 ⇒ 47

Angle 2 ⇒ 52

Angle 3 ⇒ x

Let's solve your equation step-by-step.

47 +  52 + x = 180

Step 1: Add the LHS.

47 +  52 + x = 180

99 + x = 180

Step 2: Subtract 99 from both sides of the equation.

99 + x = 180

99 + x - 99 = 180 - 99

x = 81

∴ The third angle measures 81°.
