Question

Find b in right triangle

Explain the answer please

​

Answer 1

37+108+a=180
a=180-108-37=35
37+28=65
65+35+b=180
b=180-65-35=80

Answer 2

Answer:

80⁰

Step-by-step explanation:

let the top of the triangle is C and D is the point between A and B

then ABC is a triangle whose two angles are 108⁰ and 37⁰ respectively..

so angle A is 180⁰-(108⁰+37⁰)=35⁰

now the angle C is of triangle ABC is 37⁰+28⁰=65⁰

so the angle B is 180⁰-(35⁰+65⁰)=80⁰
