Answer:
z=40 degrees
x=90 degrees
y=40 degrees
Step-by-step explanation:
To solve z you know that 50+90+z= 180 degrees. So z equals 40. To solve x you subtract 90 from 180 to get 90 degrees. To solve you add 50+x+y. You know that x= 90. You would add the angles together to get 180 degrees. 50+90=140 and 180-140 equals 40. Sorry if i'm wrong.
F(x) = 9x²<span> - 5x + 2
</span>f(-2) = 9(-2)² - 5(-2) + 2
<span>f(-2) = 36 + 10 + 2
</span><span>f(-2) = 48</span>

Answer: sin(C) = 3/5</h3>
==========================================================
Explanation:
Recall that sine is the ratio of opposite over hypotenuse.
For angle C, the opposite side is AB = 24 as this leg is furthest as possible from angle C. The hypotenuse is always opposite the 90 degree angle.
So,
sin(angle) = opposite/hypotenuse
sin(C) = AB/AC
sin(C) = 24/40
sin(C) = (8*3)/(8*5)
sin(C) = 3/5
If you want to find the measure of angle C, then you apply the arcsine rule to both sides. Inverse sine is the same as arcsine.
<u><em>Answer: x=8 and 8=x. *The answer must be have positive sign.*</em></u>
Step-by-step explanation:
addition property of equality is adding the same number to both sides of an equation does not change the equation.
a+c=b+c
distributive property: a(b+c)=ab+ac
add the numbers.
7x-3x=4x
4x-8=24
add by 8 both sides of an equation.
4x-8+8=24+8
simplify by equation.
24+8=32
4x=32
divide by 4 both sides of an equation.
4x/4=32/4
simplify by equation.
32/4=8
32/8=4
8*4=32
4*8=32
It change negative to positive.
x=8 and 8=x
Hope this helps!
Thanks!
Have a great day!
