Answer:
Cos 25°=Sin65°=0.9063
Step-by-step explanation:
-Complimentary angles generally refer to the two acute angles of a right triangle.
-The two angles add up to 90º.
Let A and B be the two acute angles. Their trigonometric relationship is such that:

Therefore,
The complementary angle of 25° is 65°
Cos 25°=Sin65°=0.9063
Answer:
134/25
Step-by-step explanation:
5 9/25 > 5 * 25 = 125 + 9 = 134. > 134/25
I guess you need help with #3
So you have to 642 by 5
By the way, this is a great question for a calculator to check your answer
The answer 128.4
Answer: Kim took 50 minutes to read the third book.
Step-by-step explanation: If you substract 120 - 15 = 105. Then divide 105 / 3 = 35. And finally add 35 + 15 = 50.
<u>Statement</u><u>:</u>
R is the midpoint of QS.
<u>To </u><u>find </u><u>out:</u>
The measure of QS.
<u>Solution</u><u>:</u>
- QR + RS = QS
- Since R is the midpoint of QS, then QR = RS.
- QR = 2x + 16, RS = 5x - 17.
- Therefore, 2x + 16 = 5x - 17
- or, 2x - 5x = -17 - 16
- or, -3x = -33
- or, x = -33 ÷ -3
- or, x = 11
- Therefore, QR = 2(11) + 16
- = 22 + 16 = 38
- So, QS = 2QR
- = 2 × 38
- = 76
<u>Answer</u><u>:</u>
QS is 76.
