Answer 2

Question:-

Two angles in a triangle measure 102 degrees and 67 degrees. What is the measure of the third angle?

• 11 degrees
• 78 degrees
• 113 degrees
• 169 degrees

Hint:-

We already know that the sum of all angles of a triangle is 180°

Answer:-

• 11 Degrees

$\huge{ \sf{ \red{ \underline{ \underline{Solution:- }}}}}$

• Let the third side be x.

$\green{↣} \bf \: 102 + 67 + x =180 \degree$

$\red↣ \bf169 + x = 180 \degree$

$\pink↣ \bf \: x = 180 - 169$

$\orange↣ \bf \: x = 11 \degree$

${ \underline{ \underline{\huge{ \color{gold}{ \sf \: Verification}}}}}$

By keeping 11° at the place of x we will check whether our answer is correct or not.

$102 \degree + 67 \degree + 11 \degree$

$= 180 \degree$

Hence proved that our answer is correct ✔✔
