Answer:
15/7 = 2 1/7
16/6 = 2 4/6
12/5 = 2 2/5
48/7 = 6 6/7
Step-by-step explanation:
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
There can not be equal sharings since 16/5 does not equal a whole number! Good luck :)
Answer:35 you are welcome
Step-by-step explanation:
Since x and 82° lie along the same straight line, they must sum to 180° so:
x=180-82
x=98°
