Question

3. Could I find the two missing angle measures if I know some of the side lengths of a right triangle?

Answer 1

yes

Answer 2

um

Answer 3

use Pythagoras theorem \[b^{2}+c^2 = a^2\]

Answer 4

ohh yea ty

Answer 5

also you can use 'sohcahtoa'

Answer 6

you you know what i mean?

Answer 7

yea sin tan and cos

Answer 8

Pythagoras is useful to get lengths of the sides and sin cos and tan can be used to get the angle's or side length also.

Answer 9

sin cos and tan there are three variables the angle and two sides as long as you have two values you can solve for the other.

Answer 10

and you also know that if its a right triangle the sum of angle adds to 180 and one angle is always 90.

Answer 11

ok kool ty

Answer 12

yw

Answer 13

say the oposite and the base are 4.25 whats the hypotenuse length like how do i work it out

Answer 14

well 4.25 = a 4.25=b and h=? \[a^2+b^2=h^2 \]

Answer 15

solve for h

Answer 16

is one way.

Answer 17

um 36.125

Answer 18

i feel like i did it wrong

Answer 19

so you have \[36.125=h^2\]

Answer 20

yea it just doesnt seem right

Answer 21

its right

Answer 22

you need to get rid of the square

Answer 23

so remember you can do what every you want to on the right of the equation as long as you do it to the left.

Answer 24

so it a trianlge automaticly equals 180 and i have 90 and 36 which equals 126 then the other angle is 54
