Question

Use the right triangle to solve the triangle
b=4, c=6
Find a, A, B

Answer 1

Okay, let's find the sides first.. Do you know the Pythagorean Theorem?

Answer 2

Yes

Answer 3

How could we apply this in this equation?

Answer 4

To find a

Answer 5

Brillant! Could you set up an equation for a?

Answer 6

a^2+4^2=6^2
a= sqrt 20

Answer 7

Awesome! Now have you learned what SOHCAHTOA is?

Answer 8

Yes

Answer 9

Nice! So we could say sin(B) = b/c right?

Answer 10

It's crucial you understand that part, do you understand it?

Answer 11

Yes

Answer 12

Okay so sin(B) = 2/3 and do arcsin on both sides with your calculator and you should get what B is!

Answer 13

sin(B)..
arcsin (sin(B)) = B

Answer 14

I have to go but I hope you understand the jist of this.
