Answer 1

What do you know about the total measure of all the angles in a triangle?

Answer 2

idk

Answer 3

Okay, well, all the angles in a triangle add up to be 180 degrees. (bc it's half of a square, and all of the square's angles equal 360 degrees)
Anyway, you already have two of the three angle measures, so you can set up an equation basically 87+32+x=180.
Now, what would x be?

Answer 4

x=61

Answer 5

Yes! Now, do you know what type of angle 1 and C form?

Answer 6

not really

Answer 7

Okay, well, the form a supplementary angle. Do you know what a supplementary angle is/what the measure of it is?

Answer 8

180

Answer 9

Yes! So, now you can set up another equation.
61+x=180
(x, in this case, will be the measure of angle one)
Solve for x, and you have the measure of angle 1

Answer 10

so angle 1 = 119

Answer 11

Mhm :)

Answer 12

yay thank u (:

Answer 13

No problemo :)
