Since the exterior angle and other angle must be complimentary the angle in the triangle must be 60°. Since it’s a right triangle one angle must be 90°. A triangle must add up to 180°. 60°+90°=150°. 180°-150°=30°. So your angles in the triangle would be 60°, 90°, and 30°

round as needed

Step-by-step explanation:

Law of Cosines

c^2 = a^2 + b^2 - 2abCosC

c^2 = 125^2 + 210^2 - 2(125)(210)Cos73

c^2 = 15,625 + 44,100 - 15349.5

c^2 = 44,375.5

c = 210.654931107724132

Zepler [3.9K]

Answer:

35.786

12(3) - 3(1/2)/4(3) - 5

This is then further simplified to:

36 - 1.5/7

And when you divide 1.5 by 7, the number (rounded) is .214.

Thus, subtract, and gain the final answer of 35.786.
