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

Rufina [12.5K]

I sent help but no one answered :(

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
mestny [16]

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.

I forget how to do this,thanks for the help!
miss Akunina [59]

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
