Answer:
15;9;-8
Step-by-step explanation:
1. 5/3x-3=2/3x+12
x=15 once you combine like terms
2. 5x+35-3x+12=7x+2
2x+47=7x+2
5x=45
x=9
3. 12x+20-3=9x-7
12x+17=9x-7
3x=-24
x=-8
Answer:
The answer to your question is x = 17.32; y = 8.67
Step-by-step explanation:
Process
1.- Use trigonometric functions to find x and y
a) sin Ф =
Ф = 60°
opposite side = 15
hypotenuse = ?
hypotenuse = 17.32
b) cosФ =
y = 8.67
Answer:
90 pages
Step-by-step explanation:
30% complete
70% to go = 63 pages
t = total number of pages
0.7t = 63
∴ t = ⁶³/₀.₇
⁶³/₀.₇ = 90
Answer:
Zb=62
Step-by-step explanation:
Two angles are complementary when they add up to 90 degrees.
90-28=62
