Step-by-step explanation:
AC = 20
AB = 18
BC² = 20²+ 18² -2•20•18•cos(52°)
BC² = 280.72
BC = √280.72
BC ≈ 16.75
Angle C:
18² = 20² + 16.75² -2•20•16.75•cos(C)
324 = 400 + 280.72 -670•cos(C)
cos(C) = -356.72/-670
cos(C) ≈ 0.53
acos(0.53) = C
C = 57.8°
Angle B:
180-52-57.8 = 70.2°
Answer:
(29-26) * 3 = 9
Step-by-step explanation:
Answer:
option c
Step-by-step explanation:
first, find the y-intercept:
the y-intercept is the point where the line intersects at the y-axis, in this case, at 3.
therefore, we can rule out all options except c, sincee the y-intercept is 3
hope this helps :)
Answer:
The sign inside the absolute value would change it from negative to positive.
Step-by-step explanation:
The answer should be 37
2(x+8) = 3(x-7)
distribute
2x+16 = 3x-21
Subtract 2x from both sides
2x+16-2x = 3x-21-2x
16 = x-21
Add 21 to both sides
16+21 = x-21+21
