Since it's a right triangle, we can use SOH-CAH-TOA. So tan(x) = opposite/adjacent = 5/20
tan(x) = 1/4 = 0.25
x = arc-tan (0.25) = 14.04°

Solve the equation (y-10)^2=0

Dvinal [7]

Answer:

y=10

Step-by-step explanation:

(y-10)^2=0

Take the square root of each side

sqrt((y-10)^2)=sqrt(0)

y-10 =0

Add 10 to each side

y-10+10=0+10

y = 10

CIRCLE question is in the picture

Dennis_Churaev [7]

Answer:

27π cm² or 84.8 cm²

Explanation:

$\sf Formula \ for \ area \ of \ sector = \dfrac{\theta}{360 } \ x \ \pi (radius)^2$

Shaded region angle: 360° - 90° = 270°

Given radius: 6 cm

Applying formula:

$\rightarrow \sf \dfrac{270}{360} \ x \ \pi (6)^2$

$\rightarrow \sf 27\pi$

$\rightarrow \sf 84.823 \ cm^2$

$\rightarrow \sf 84.8 \ cm^2 \quad (rounded \ to \ nearest \ tenth)$

4 - 3x > 13 (Solve for x)

Fudgin [204]

Answer:

X < -3

Step-by-step explanation:

4 - 3x > 13

First move the 4 over, subtract from both sides:

-4 + 4 - 3x > 13 - 4

-3x > 9

Now move the -3 over, divide on both sides.

When you multiply or divide by a negative, you have to reverse the sign.

-3x/-3 < 9/-3

X < -3
