Question

find the value of x​

Answer 1

Answer:

=3×-1+×+8+×+3=180

=5×=170

=×=34

c=42

A=34×3-1=101

B=37

Answer 2

Answer:

x=35

Step-by-step explanation:

As ABC is a triangle,

angle A+angle B+angle C =180

(x+3) + (3x-1) + (x+8)=180

x+3+3x-1+x+8=180

4x+3-1+8=180

4x+10=180

x+10=45

x=45-10

x=35
