Question

Plz Help due in 10 min If triangle ABC has the following angle measurements, what is the value of x?

∠A=4x − 17


∠B= 3x + 8


∠C= x+ 13
x = 22


x = 23


x= 176


x = 3.7

Answer 1

Explanation:

4x-17+3x+8+x+13=180

8x+4 =180

8x=176

X=22

Answer 2

x = 22

Explanation:

<A + <B + <C = 180

<A = 4x - 17

<B = 3x + 8

<C = x + 13

4x - 17 + 3x + 8 + x + 13 = 180 Collect the like terms

8x + 4 = 180 Subtract 4 from both sides

8x = 180 - 4

8x = 176 Divide by 8

x = 176/8

x = 22
