Answer:
18° and 72°
Step-by-step explanation:
Complimentary angles form 90°
We have an angle (x) 4 times larger than the other (y).
Well actually, a system of equations isn't required, so forget about x and y, just divide 90 by 5. This gives you 18, one of the angle's measurements is 18°. Multiply 18 by 4 and get 72. The other angle's measurement is 72°.
Answer:
Step-by-step explanation:
<u>Subtract the values:</u>
- 19 1/12 - 8 5/12 =
- 18 13/12 - 8 5/12 =
- 18 - 8 + 13/12 - 5/12 =
- 10 + 8/12 =
- 10 8/12 =
- 10 2/3 in
Sin D= opp./hyp. = 35/37
cos D= adj./hyp. = 12/37
tan D= opp./ adj. = 35/12
