Answer:
b = 7
Step-by-step explanation:
3b - 4 = 17 is 7 because you are trying to isolate the variable. First, you add 4 to each side (17 + 4 and 4 + 4). Since, 17 + 4 is 21, 3b = 21. Now, since the inverse operation of multiplication is division, we divide 3 by both sides. 17 divided by 3 is 7. So b = 7.

Answer:
40.1°
Step-by-step explanation:
JK is the hypotenuse of the right triangle.
For angle J, KL is the opposite leg.
sin A = opp/hyp
sin J = 4.7/7.3
J = sin^-1 4.7/7.3
J = 40.1
Answer: 40.1°
