4 5/8
4 1/8
20 1/2
4 3/8
0.25 or 16
Answer:
1.98
Step-by-step explanation:
Use SOH-CAH-TOA:
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
Here, we're given the hypotenuse is 4.5, and we want to find the side opposite of the 26° angle. So we should use sine.
sin 26° = x / 4.5
0.44 = x / 4.5
x = 1.98
-0.6875 is the answer to number 5
Alrighty, so, without the picture and the clues given I'm going to assume the image you have looks like two angles coming from the middle of a straight line. A straight line is equal to 180 degrees. 180 degrees minus 168 degrees equals 12.
