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.

Find f(-2).<br><br> f(x) = 9x2 - 5x + 2 <br> A) 14 <br> B) 18 <br> C) 28 <br> D) 48
kifflom [539]
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>

<h3>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.

7x-3x-8=24 what is the value of x
Ann [662]

<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!
