12x > 9(2x-3)-15
distribute the 9
12x > 18x-27 -15
combine like terms on the right side
12x > 18x-42
subtract 18x from both sides
-6x > -42
divide both sides by -6
x = -42 / -6 = 7
x >7
30X15=450. 450:100= 4,50. 30+4,50= 34,50

Answer:
- sin(θ) = 4/5
- cos(θ) = 3/5
- tan(θ) = 4/3
Step-by-step explanation:
The mnemonic SOH CAH TOA was created to help you remember the relevant trig relationships. It is intended to remind you ...
Sin = Opposite/Hypotenuse
sin(θ) = 4/5
Cos = Adjacent/Hypotenuse
cos(θ) = 3/5
Tan = Opposite/Adjacent
tan(θ) = 4/3
__
In a right triangle, the opposite side (PQ) is the one that is not part of the angle (∠R = θ). The adjacent side (QR) is the shorter side that makes up the acute angle. The longest side (PR) is the hypotenuse.
Answer:
32
Step-by-step explanation:
first simplify the exponent
4^2 = 16
so u would get
2 + 16 / 2 • 5 - 10
then divide and multiply to get
2 + 8 • 5 - 10
2 + 40 - 10
then add and subtract
42 - 10 = 32
