Question

Pls help I don’t know how to do this

Answer 1

1: A triangle's angles add up to 180

180 - 130 = 50

50 / 2 = 25

x = 25

2: The sides given will be equal as this is a right-triangle

24 = 3(x + 2)

24 = 3x + 6

18 = 3x

x = 6

3: There is a lot of writing so I am unable to see the original triangle

(sorry *nervous sweat*)

4: A triangle's angles add up to 180, and the two sides given will be equal

5y = 20

y = 4

The angles in the bottom-most triangle are all equal to 60 as 180 / 3 = 60.

90 - 60 = 30.

x = 30

Have a nice day!
