Question

TRIANGLE ABC IS SIMILAR TO TRIANGLE PQR ANGLE B=40°,ANGLE P=70°.THEN WHAT IS VALUE OF ANGLE R? JUSTIFY YOUR ANSWER

Answer 1

Answer:

we know that angle b= 40 degree and Angle P = 70 degree if triangle ABC is equal to triangle pqr, so angle P = 70 degree = angle A similarly angle b = 40 degree =angle Q now. in triangle pqr angle P =70 degree and Angle Q = 40 degree

now,

in triangle pqr angle P + angle Q + angle r =180 degree? angle sum property e of triangle

hence;

70 degree + 40 degree + angle R = 180 degree

110 degree + angle R = 180 degree

angle r are = 180 degree- 110 degree

angle R= 70 degrees
