Answer:

See explanation

Step-by-step explanation:

(4)

Using the sine ratio in the right triangle

sinΘ = $\frac{opposite}{hypotenuse}$ = $\frac{7}{9}$ , thus

Θ = $sin^{-1}$ ( $\frac{7}{9}$ ) ≈ 51.1°

(5)

Using the tangent ratio in the right triangle

tanΘ = $\frac{opposite}{adjacent}$ = $\frac{4}{5}$ , thus

Θ = $tan^{-1}$ ( $\frac{4}{5}$ ) ≈ 38.7°

Solve for x <br> -2^2(-5x+10)=100

masha68 [24]

Answer:

$x=7$

Step-by-step explanation:

Hi there!

$-2^2(-5x+10)=100$

Solve -2^2:

$-4(-5x+10)=100$

Divide both sides by -4:

$\displaystyle \frac{ -4(-5x+10)}{-4}=\frac{100}{-4} \\\\-5x+10=-25$

Subtract 10 from both sides:

$-5x+10-10=-25-10\\-5x=-35$

Divide both sides by -5:

$\displaystyle \frac{-5x}{-5} = \frac{-35}{-5} \\\\x=7$

Therefore, x = 7.

I hope this helps!
