x 11.28
Therefore, he can spend less than or as much as $11.28.
Question
Step-by-step explanation:
The solutions would be
x= (-9/8)+(1/8)√33
and
x=(-9/8)+(-1/8)√33
40.71428571428571
If you want you can round it
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°
