Question

∆ ABC ~ ∆ PQR, <A=53°and <Q= 77° find <B?
ANSWER Me Please ​

Answer 1

Answer:

Angle B is = 50 degree

Step-by-step explanation:

we will use angle sum property,

aA + aB + aC = 180

53+ aB + 77 = 180

aB + 130 = 180

angle B = 180-130

= 50 degree

Answer 2

Answer:

Here is the answer to your question

Given,

∠A = 53° , ∠Q = 77°

∴ ∠A + ∠Q + ∠R = 180°

= 53°+77°+∠R = 180°

= ∠R = 180° - 53° - 77°

= ∠R = 50°

Hence, the correct answer is 50°
