I saw the video and it just confused me more

Answer 6

plzzz help!

Answer 7

How many degrees are there in a triangle?...

And how many degrees are already given?

Answer 8

since it is a right triangle, you automatically have the 90 degrees. Then your given angle which is 20.
90+20=110

then you take that number and subtract it by 180 because that's how many degrees are in a triangle.
180-110=70.

Angle A = 70 degrees

Answer 9

In the case, the best trig function to use would be Tangent (tan) which is opposite over adjacent. so if you were to do

tan20 = (30/x)

then you would want to solve for x. So multiply x by both sides:

xtan20 = 30

then divide both sides by "tan20"

x= 30/(tan20) = 82.42

Answer 10

then to find AB, just use Pythagorean Theorem (a^2 + b^2 = c^2)

30^2 + 82.42^2 = 7693.06

then take the square root of that and you will get 87.71.
