Question

Geometry help @jhonny9

Answer 1

so sin 60 is given
and you know that there is a right angle with measure of 90 degrees

how many will be the 3rd angle measure ?

Answer 2

together give up 180 degrees

Answer 3

the 3rd measure = 180 -(90+60)

Answer 4

3rd measure = 180-150

3rd measure = ?

Answer 5

are you here pls ?

Answer 6

@supie

Answer 7

i think it's good to point out first thing that this si a 30, 60, 90 triangle, since it's 1, 2, sqrt 3

Answer 10

going off of the fact that this is a special right triangle, u can do this pretty good with a picture. \[\sin(60)=\sqrt{3}/2\]
This means the hypotenuse is 2. while teh opposite side to this angle is sqrt(3)

This is a right triangle so u can use pythagorean theorem to find that adjacent side length
\[a^2+b^2=c^2\]
Once you find that last side length, u can do this but some hints are to not forget that cos is adjacent/hypo and the answer choices are asking about any of the 2 angles, so its adjacent/hypo with respect to what angle is what you are looking for

Answer 11

lmk if u need more clarification
