A. 25 degrees

B. 47 degrees

C. 22 degrees

D. 43 degrees

Answer 1

@dude

Answer 2

Can you find A and B in this picture? I'll slowly get you to angle alpha

Answer 3

yes

Answer 4

Alright so what's A and what's B?

If you need help just say you don't know

Answer 5

43 and 25

Answer 6

Uh actually

A is inside a triangle.

And all angles inside a triangle add up to 180

So 90 + 25 + A = 180

right?

A = 180 - 90 - 25
A = 65

Answer 7

And this is ALWAYS true:


A 90-degree angle is always next to another 90-degree angle because it makes a straight line.

So B = 90

Answer 8

I updated my diagram: Can you find C and D?

Answer 9

If you don't know just say so and I'll tell you.

Answer 10

no

Answer 11

i might be wrong

Answer 12

As you can see every angle inside a triangle adds up to 180

Something else you should know is that every angle inside a quadrilateral adds up to 360

Answer 13

Since every angle inside a quadrilateral adds up to 360

Angle A + 90 + 90 + 133 = 360

Angle A would be 360 - 133 - 90 - 90
which is 47

Answer 14

hold on a second I might've messed up somewhere...

Answer 15

yeah I made a mistake up there
I fixed it

Answer 16

It's actually 22

Answer 17

oh i see now 22 degrees i had to look back and see it is 22 not 47
