Answer:A,C,E
Step-by-step explanation:
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:p=7
Step-by-step explanation:because 4 x 7 =28
Answer:
No
Step-by-step explanation:
note
= 1.4
and sinA is defined for - 1 ≤ sinA ≤ 1
Thus sinA ≠
