The measures of the angles of a quadrilateral are in the
bearhunter [10]

Answer:

140

Step-by-step explanation:

Consider a square for just a second. It has 4 angles each of 90 degrees. The total number of degrees in a square is 4 * 90 = 360.

It should be at least an appeal to your intuition to say that a quadrilateral has a total of 360 degrees.

Therefore the ratio you have been given must have 4 angles that add to 360.

2x + 3x + 6x + 7x = 360

18x =360

x = 20

So the 4 angles are

2* 20 = 40

3*20 =  60

6*20 = 120

7*20 = 140

Total    360

The largest angle is 140

yaroslaw [1]

Answer:

15 teachers

Step-by-step explanation:

Given:

number of children is c

number of teachers is t

\frac{c}{t} = \frac{14}{3} (rearrange)

t = \frac{3}{14} x C

When C = 70,

t = \frac{3}{14} x 70

t = 15 teachers
