Answer:
a = 102.05
b = 393.76
B = 93°
Step-by-step explanation:
The law of sines tells you ...
a/sin(A) = b/sin(B) = c/sin(C)
Since the sum of angles in a triangle is 180°, angle B must be ...
B = 180° -72° -15° = 93°
and the unknown sides must be ...
a = c/sin(C)·sin(A) = 375·sin(15°)/sin(72°) ≈ 102.05192
B = 93°
b = 375·sin(93°)/sin(72°) ≈ 393.75796

The rounding requirement got cut out of your picture, so we can't help you with that.
Since they share the same angle measurement, and 4 is smaller than 158 degrees, you subtract 158 from 180 and angle 4 = 22 degrees
Answer:
1. A. 4 terms
There are 4 different values in the expression, so therefore there are 4 terms.
2. D. 3x^2 + 6x + 10
To get the answer...
start with the original expression: 3x^2 + x + 10 + 5x
add the like terms together, in this case you'd add x + 5x
you'll get: 3x^2 + 6x + 10
