Answer:
A = 52°, a = 149.2, c = 174.3
Step-by-step explanation:
Technology is useful for this. Many graphing calculators can solve triangles for you. The attachment shows a phone app that does this, too.
___
The Law of Sines can give you the value of c, so you can choose the correct answer from those offered.
c = sin(C)·b/sin(B) = sin(113°)·49/sin(15°) ≈ 174.271 ≈ 174.3 . . . . . third choice
Aruthmetic sequene is
an=a1+(n-1)d
where d=common difference between terms
adds 6 every time
d=6
first term is 8
a1=8
8+6(n-1)

8+6n-6
8-6+6n
2+6n is answer

Answer:
-1.8 =x
Step-by-step explanation:
12(x+3)=-8x
Distribute
12x +36 = -8x
Subtract 12x from each side
12x-12x +36 = -8x-12x
36 = -20x
Divide each side by -20
36/-20 = -20x/-20
-9/5 = x
Changing to decimal form
-1.8 =x
Answer:
y = 6x - 24
Step-by-step explanation:
Slope intercept form: y = mx + b.
Fill in x, y, and the slope to solve for b as follows:
First find the slope.
60 - 6
14 - 5
54/9
Slope = 6
y = 6x + b
(6) = 6(5) + b
6 = 30 + b
Subtract 30 from both sides.
-24 = b
y = 6x - 24
