Answer:

Third angle = 120 degrees

All the angles add up to 180 degrees.

Call the smallest angle x, so the second will be 2x and as the third is three times the second it will be 6x. We have:

x+2x+6x=180

9x=180⇒x=20

The third angle is 6x=120

What is the measure of angle A?
fgiga [73]

Answer:

∠A=65º

Step-by-step explanation:

  • A angle of a line is 180º, so we can say that angle ABC=(180-6x)º
  • The interior angkes of a triangle is 180º, so (x+40)º+(3x+10)º+(180-6x)º=180º
  • Remove parenthesis, x+40+3x+10+180-6x=180
  • Combine like terms, -2x+230=180
  • Subtract 180, -2x=-50
  • Divide by -2, so x=25

Now:

  • ∠CAB=(25+40)º=65º
  • ∠ABC=[180-6(25)]º=30º
  • ∠BCA=[3(25)+10]=85º

Select the correct answer from each drop-down menu.

In 20 minutes, John can wrap 10 small boxes and Hank can wrap 12 small boxes. So, Hank can wrap more small boxes in 20 minutes than John can.

Step-by-step explanation:

Given,

John wraps;

2 small boxes = 4 minutes

1 small box = \frac{4}{2} = 2\ minutes

In 20 minutes,

20 minutes = \frac{Total\ time}{Time per box} = \frac{20}{2}

20 minutes = 10 small boxes

Hank wraps;

3 small boxes = 5 minutes

1 small box =\frac{5}{3}\ minutes

In 20 minutes = \frac{Total\ time}{Time per box} = \frac{20}{5/3}

20\ minutes=\frac{20*3}{5}\\20\ minutes=\frac{60}{5}\\20\ minutes= 12\ small\ boxes\\

In 20 minutes, John can wrap 10 small boxes and Hank can wrap 12 small boxes. So, Hank can wrap more small boxes in 20 minutes than John can.
