Question

Does anyone know how to find the value of x in this?
I've done one question like it before but I'm confused.

Answer 1

I think because of the shape is a triangle and your trying to find x it would be 78 because a triangle is an equal shape which all sides are equal

Answer 2

78 isnt one of my options :/
Right now im using the triangle sum propert which means all angles added together equal 180 degrees, thank you though :3

Answer 3

property*

Answer 4

ohhh so your trying to get the triangle to equal to 180?

Answer 5

yes but there are two triangles here, so in order to find the value im looking for i have to find the value of the other angle in the other triangle first.

Answer 6

sooo 84 + 70 = 154 so 180 - 154 = 26.

Answer 7

so the first angle on the first triangle is 26

Answer 8

well both ends of the triangle equal 78 then 78+78=156 then 180-156=24 that's the top of the triangle and then add up 78 78 and 24 a you get 180

Answer 9

and the triangle is called a scalene triangle btw that is why both ends are equal

Answer 10

You're actually right.. 78 is the answer. I wonder why it's not one of my answers..
My answers are 32, 48, 70, & 76. But if it were to be 76 that would only be 178 and not 180.

Answer 11

yeah you have to ask your teacher about that Lol.Thats just the way I learned it in geometry

Answer 12

okay lol xD
thanks :)

Answer 13

no problema(:
