Question

Find the values of x and y. (Could someone explain this to me?)
A. x = 22, y = 68
C. x = 90, y = 68
B. x = 68, y = 22
D. x = 90, y = 22

Answer 1

hope you can tell those are degrees..

Answer 2

Do you know the identities of isosceles triangles?

Answer 3

i thought x would =90 because the triangle is at 90 degrees.

Answer 4

its a triangle with 2 equal sides if thats what you mean.

Answer 5

..i still need help with this..

Answer 6

Yes. It is true that x = 90 because of perpendicularity.
Let me tell you one more characteristic of isosceles, their base angles are also equal. Now, can you solve for y now?

Answer 7

x=90 y=68

Answer 8

right?

Answer 9

No. :)

Answer 10

The 3 angles of a triangle always sum to 180 degrees.

Answer 11

ohh

Answer 13

so its 180-90 ?

Answer 14

No.... you are leaving out the other angle. :)

Answer 15

There are 3 angles... so if you know 2 of them, you know the 3rd.

Sum the measures of the 2 that are known, and then subtract that from 180.

Answer 16

what the hey... a report abuse button just popped up?? ...anyways you add up both those angles and then subract them from 180 ?

Answer 17

so i would get 22 right ?

Answer 18

Yes. Or to simplify it - when you know that ONE angle is a right angle (90 degrees), then the other 2 angles must add up to 90 degrees. So just subtract the one non-right angle measure from 90 degrees.

Answer 19

@HendersonNeedsYurHelp 2y =180-( 2*68), then. Therefore what is y?

Answer 20

y=22 yttrium

Answer 21

thanks guys :) i get it now!

Answer 22

Right. :)
