Answer:
Step-by-step explanation:
<u>Use the law of cosines:</u>
- cos F = (e² + g² - f²)/2eg
- cos F = (2.6² + 8.3²- 7.2²)/2(2.6)(8.3)
- = 0.5516
- ∠F = arccos 0.5516
- ∠F = 57° (rounded to the nearest degree)
Sin r = 20/29
SOHCAHTOA
R:
(O) opposite - 20
(A) adjacent - 21
(H) hypotenuse - 29
A is the answer because u have to shift up two units and move it right 8 units
