All 3 angles of a triangle add up to ? degrees?

#

,tex $a = 180 \left( n - 2 \right)$

#

this formula can be used to find the total sum of all angles in a polygon with n sides

#

in this case, the polygon has 3 sides, so n = 3

#

so the total sum of all angles in any triangle (including the given one) is 180

#

and we are already given two of the three angles

#

m__/__G = 180

#

and it isnt stated in numbers, but an angles marked with an L implies it is a right angle, so it measures 90 degrees

#

now lets solve for EF and EG

#

there is a geometry rule that says, in any given triangle, the ratio of any angle to the length of said angle's opposite side is the same for all three pairs

#

its kinda hard to understand, so ill show u

#

luckily, one of the pairs of angle and opposite side is given to us in the problem

i know from the unit circle that sin(90) = 1
