Question

Is there anyone smart enough to help me on this problem?

Answer 1

What is the value of X in this triangle?

Answer 2

69 degrees.
All angles in a triangle add up to 180 degrees.

Answer 3

How do I find X and Y of a triangle?

Answer 4

the measures of the missing angles are the same because they are base angles of the isosceles triangle.

Answer 5

That's how 69 was found
(180 - 42)/2

Answer 6

How do I find the X and Y of this one?

Answer 7

y = 25
x = 90

Answer 8

But how did you get that?

Answer 9

The angle across from 65 must be 65 then the top must be 50 split that in half and you've got 25 25 + 65 = 90 180 - 90 = 90

Answer 10

yes

Answer 11

How do i do this one?
In an A-frame house, the two congruent sides extend from the ground to form a 52° angle at the peak. What angle does each side form with the ground?

Answer 12

yes

Answer 13

180 - 5x = 5x - 50
180 = 10x - 50
230 = 10x
23 = x

Answer 14

22 is the closest one on here

Answer 15

yeah that's it I copied the problem wrong it's -40 not -50 sorry

Answer 16

You just need to know what a supplementary angle is

Answer 17

* supplementary angles

Answer 18

supplementary angles add to 180. understand?

Answer 19

The octagon in the figure is equiangular and . What would you need to know to find mACB?
And this one? :D

Answer 20

And after this, one more? The whole thing was like 21 questions. Lol

Answer 21

oh and where it says "and" i forgot to put, AB congruent to AC
