Question

Can someone check my answers for the Triangle Sum Theorem worksheet please?

Answer 1

recheck your number 3 and 5

Answer 2

90 + 40 + 150 = 280

Answer 3

on 5, notice the tickmarks on the left and right hand sides, that means those 2 legs are equal to each other, thus the angles they'd make at the bottom are also equal to each other

Answer 4

so it will be 100 then and not 150?

Answer 5

well, the sum of all internal angles in a triangle are 180 degrees, you have there a 40 and a 90 one already, so "x" will be the difference

Answer 6

180 - ( 90 + 40) = x

Answer 7

okay

Answer 8

I was still on number 3 sorry :/

Answer 9
