Can someone help me on this problem?

X= 70 degrees

Step-by-step explanation:

Its quite simple.

You are going to put this into an equation (Note that ALL Real Triangles equal 180 degrees from the inside)

38 + x + x + 2 = 180

combine like terms

40 + 2x = 180

subtract 40 from both sides

40 + 2x = 180

-40 -40

2x = 140

divide both sides by 2 to get X alone

2x = 140

2 2

x = 70

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
