Question

The angle A of a triangle ABC is equal to the sum of the other two angles. Also the ratio of the
to the angle C is 2:3. then three angles are
(4) 90°,609,30
(3) 95°,319,54
(1) 90°,369,54 (2) 959 49º 36°​

Answer 1

Answer:

4)090,609,30 is the answer

Answer 2

hey there it's simple

we know that sum of angles in triangle is 180°

given that

A=B+C

now A+B+C=180°

A+A=180°

2A=180

A=90°

NOW B+C=90

GIVEN THAT B:C=2:3

now B=2K

C=3K( WHERE K IS CONSTANT)

NOW B+C=90

2K+3K=90

5K=90

K= 90/5

k=18

now B=2(18)

B=36

C=3(18)

C=54

now the angle s are

A=90°

B=36°

C=54°
