Quadrilateral defg is a rectangle.
if the measure of angle edf = 5x-3 and the measure of angle dfg = 3x+7,
find the measure of angle edf.
a. 20
b. 22
c. 18

e EDF= Measure of angle DFG

b.22.

Step-by-step explanation:

We are given that quadrilateral DEFG is a rectangle.

We know that every angle of reactangle is of 90 degrees.

We are given that

Measure of angle EDF=5x-3

Measure of angle DFG=3x+7

We know that every every angle of rectangle is equal.

Measure of angle EDF=Measure of angle DFG

By using subtraction property of equality

By simplification

By using subtarction property of equality

By using division property of equality

By simplification

Substitute the value x=5 then

Measure of angle EDF=

Measure of angle EDF=25-3

By simplification

Measure of angle EDF=22

Hence, the measure of angle EDF=.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

-2 is the right
