Question

In the figure below, ABC is a right triangle. a + b = 150 degrees, and c + d = 35 degrees. Find x.

Answers:


150

115

85

25

Answer 1

All three angles of any triangle a + b+ c will add up to180 degrees, correct?

Answer 2

yes.

Answer 3

a+b+c =180
from the picutre you drew, it's obvious that angle b is at 90 degrees.
so b=90
a+90+c =180
to to isolate all the variables to one side, you'd have to subtract 90 to both sides
a+c=90

Answer 4

so, what about adc, what do you think these three triangle angles add up to?

Answer 5

the final answer would be 85 right?

Answer 6

we haven't go to the final answer yet

Answer 8

i meant bxd, sorry read your picture wrong

Answer 9

So what would b + x + d = ?
