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.
Answer:
27.9 dollars
Step-by-step explanation:
2.70= 15 percent
2.70x2=5.4=30 percent
5.4+2.70=8.1=45 percent
8.1x2=16.2=95 percent
95 percent + 15 percent=18.9
18.9=105 percent
in order to subtract 5 percent we need to find 5 percent by dividing 2.70 by 3
which = .9
18.9+9=27.9
100 percent is 27.9 dollars
Answer:
A
Step-by-step explanation:
4 ----- 2/3
15 ----- ????
multiply 15 by 2/3 and divide the result by 4 and you will get the answer.
Answer:
y = -4x + 60
Step-by-step explanation:
(0, 60) and (4,44)
Slope:
m=(y2-y1)/(x2-x1)
m=(44 - 60)/(4-0)
m= (-16)/4
m= -4
Slope-intercept:
y - y1 = m(x - x1)
y - 60 = -4(x - 0)
y - 60 = -4x
y = -4x + 60
