THe first thing we need to do is find the hypotenuse. From the tangent we know that the legs of the right triangle are 3 and 4. So this 2/3 of a special right triangle (3-4-5). Thus the hypotenuse is 5. The sin is defined as

. We know the opposite is 4 and hypotenuse is 5. Thus the sin is
Answer:
7) 38.5mi 8) 9ft
Step-by-step explanation:
7) 7 x 11 = 77
77/2 = 38.5
8) 3 x 3 = 9

Answer:
46% of 127 is 58.42
Step-by-step explanation:
46/100 = x/127
Cross multiply
46 × 127 = 100 × x
5,842 = 100x
Divide both sides by 100
58.42 = x
They would be alternate exterior so they would have to to be equal
2k + 11 = 131
-11 -11
2k = 120
