Question

help me please. what is the value of x in this diagram?

Answer 1

A: 17
B: 15
C: 105
D: 68

Answer 2

First of all, solve for y because 4y + 112 = 180

The side opposite to 4y will be the same value..
So then just solve for x :P

Answer 3

i think i need step by step help if you dont mind. :)

Answer 4

Okay, sorry.

So to solve for y, you just use the equation I gave you above which is 4y + 112 = 180.

So subtract 112 from 180 which is 68..
You divide 68 by 4 which is 17, so y = 17!

Now just multiply 4 by 17 which is 68 ..

Now look below.. V

Answer 5

so since you have 180 + 68 which is 248, so subtract 248 from 360 and you get 112 (WHAT A SURPRISE RIGHT?) It turns out to be the same as its' opposite angle..

Solve for x now..
7x + 7 = 112

Subtract 7 from both sides..
Which is 105, then divide by 7

What is 105 divided by 7? :)
