120+100+120+x+10+120+x=720
             2x+470=720
subtract 720- 470
2x=250
x=250/2
x=125
125+10=135
hope it helps

So to solve for x, you'll need to combine all the angles and equal it to 720, and from there we can solve.

120+100+120+x+10+120+x=720

Combine like terms to get 2x+470=720

Subtract 470 on each side to get 2x=250

Then just divide on each side and you'll get x=125


To find the value of the (x+10) angle, just substitute 125 for x and solve.

125+10=135

What is the value of x
9966 [12]

ANSWER

x=27

EXPLANATION

The two triangles are similar so the corresponding sides are equal.

\frac{x}{x +1 8}  =  \frac{39}{39 + 26}

\frac{x}{x +1 8}  =  \frac{39}{65}

Cross multiply to get;

65x = 39(x  + 18)

Expand:

65x=39x+702

Group similar terms:

65x-39x=702

Simplify

26x=102

Divide both sides by 26,

x=702/26

x=27
