Question

In Triangle PQR, If P 30° and Q = 50°. The measure of Angle R=?​

Answer 1

Step-by-step explanation:

hellow mate

ANGLE P :- 30°

Angle Q :- 50°

WE KNOW ALL TRIANGLE'S ANGLE MEASURE TO FORM AN ANGLE OF 180 ° in total....

SO ANGLE R :- 180° - (30°+50°)

:- 180° - 80 ° = 100° .....

hope it helps

Answer 2

Answer:

Question :-

In Triangle PQR, If P 30° and Q = 50°. The measure of Angle R=?

Answer :-

• angle QRP = 100°

Given:-

• Angle QPR = 30°
• Angle PQR = 50°

To find :-

• Angle QRP

Solution :-

$\boxed{angle \: QPR \: + angle \: PQR \: + angle \: QRP \: = 180° \: ( \: angle \: sum \: property)}$

$\implies \: 50° + 30° + angle \: QRP \: = 180° \\ \\ \implies \:angle \: QRP +80° = 180° \\ \\ \implies \:angle \: QRP = 180° - 80° \\ \\ \implies \:angle \: QRP =100°$

Hence,

angle QRP = 100°

Verification :-

$angle \: QPR \: + angle \: PQR \: + angle \: QRP \: = 180° \\ \\ 50°+30°+100° = 180° \\ \\ 180° = 180°$
