ANSWER

$x = 54\degree$

EXPLANATION

The diameter meets the tangent to the circle at right angles.

The sum of interior angles of a triangle is 180°.

This implies that

$x + 36 \degree + 90 \degree = 180 \degree$

Group the constant terms

$x = 180 \degree - 36 \degree - 90 \degree$

We simplify to obtain,

$x = 54\degree$

Jk, I got you fam

12(t + 2) + 4 ≥ - 8

12t + 24 + 4 ≥ - 8

12t + 28 ≥ - 8

12t ≥ - 8 - 28

12t ≥ - 36

t ≥ - 36 ÷ 12

t ≥ - 3

Solution:

t ≥ -3

The coffee Lily likes is composed of 97.3% water and 2.7% cocoa. The coffee John likes is composed of 96% water and 4% cocoa. Ho

30 ounces of the coffee John likes consists of

$0.96\cdot30=28.8$ ounces of water
$0.04\cdot30=1.2$ ounces of cocoa

To this mixture we're adding $x$ ounces of water, so that the new mix has a total volume of $30+x$ ounces and matches the composition of the coffee Lily likes. This means it would consist of

$0.973\cdot(30+x)=28.8+x$ ounces of water
$0.027\cdot(30+x)=1.2$ ounces of cocoa (same amount of cocoa as before because pure water is being added)

Solve for $x$ :

$0.973(30+x)=28.8+x\implies29.12+0.973x=28.8+x$

$\implies0.39=0.027x$

$\implies x\approx14.4$

###

Just to confirm: the new mixture consists of

$28.8+14.4=43.2$ ounces of water
$1.2+0=1.2$ ounces of cocoa

giving a total volume of $43.2+1.2=44.4$ ounces of coffee, and $\dfrac{43.2}{44.4}\approx0.973$ , as required.

Answer:

x=12

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees

5x+8x+2x =180

Combine like terms

15x = 180

Divide by 15 on each side

15x/15 =180/15

x=12
