Question

\angle A=8x-10 \angle B=3x+90

Answer 1

Answer:

<A=56.64

<B=114.99

<C=8.33

Step-by-step explanation:

let angle C be x

8x-10+3x+90+x=180°[sum of inside the triangle is 180°]

12x+80=180

12x=180-80

x=100/12

x=8.33

now putting the value of x

angle C is 8.33

angle A is 56.64

angle B is 114.99
