Question

Given ∆ABC congruent to ∆PQR. If <A =45°, <B= 70° then what is the

measure of <R?
step by step ​

Answer 1

Answer:

[R=65

Step-by-step explanation:

[ =ANGLE

[A=[P=45

[B=[Q=70

[C=[R=

therfore

[P+[Q+[R=180

45+70+[R=180

[R=180-115

[R=65

Answer 2

Answer:

angle R is 65°.

Step-by-step explanation:

when two triangle are congruent their angle are same and congruent. so here

angle A is equal to to angle P

angle B is equal to angle Q

angle C is equal to angle R

so here we have to calculate angle C

we know that angle's sum of triangle is 180°

then angle A + angle B + angle C = 180°

45°+70°+ angle C =180°

115°+ angle C = 180°

angle C =180°-115°

angle C = 65°

We know that angle C is equal to angle R

angle C =angle R =65°

Therefore, angle R is 65°.
