Two angles of a quadrilateral measure 245 degrees and 80 degrees. The other two angles are in a ratio of 2:5 what are the measures of those two angles?

10° and 25°

Step-by-step explanation:

The  ratio of the 2 angles = 2 : 5 = 2x : 5x ( x is a multiplier )

The sum of the 4 interior angles of a quadrilateral = 360°

sum the 4 angles and equate to 360

245 + 80 + 2x + 5x = 360

325 + 7x = 360 ( subtract 325 from both sides )

7x = 35 ( divide both sides by 7 )

x = 5

Thus

2x = 2 × 5 = 10

5x = 5 × 5 = 25

Then the 2 angles measure 10° and 25°

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
