How would you solve for side a? pythagorean theorem, cause if that's the case wouldn't
a=?
b=15
c=7
but we know that 2 sides of a triangle can't be greater than the third (or am i getting that rule wrong? )

The angle is 127°, so the Pythagorean theorem does not apply.

Generally, you would use the Law of Cosines to solve for the third side when given two sides and the angle between them.

EF^2 = 7^2 +15^2 -2*7*15*cos(127°)
EF ≈ √(400.3812) ≈ 20.00953

My guess is that you're expected to use 20 for the length of the 3rd side.

By Heron's formula, s = (7 +15 +20)/2 = 21

Area = √(21*(21 -7)*(21 -15)*(21 -20)) = √(21*14*6*1) = √1764 = 42 . . . . yd^2

More directly,
.. Area = (1/2)*7*15*sin(127°) ≈ 41.928 . . . . yd^2

U ok yeah u go do that
