Lucas is planting grass on the shaded portions of the yard. What will be the total area covered by​ grass?
maxonik [38]

Complete Question:

Lucas is planting grass on the shaded portions of the yard. What will be the total area of covered by grass? Fill in the missing.

Part A= 12 x ? = ? ft²

Part B= 0.5 x ? x 9 = ?ft²

Part C= 0.5 x 7 x ? = ?ft²

Total Area= ?ft²

Answer:

A = 108ft^2

B = 27ft^2

C = 24.5ft^2

Area = 159.50ft^2

Step-by-step explanation:

Given

See attachment

From the attachment;

Part A is a rectangle with dimension 9ft by 12ft

So,

A = 12ft * 9ft

A = 108ft^2

Part B is a triangle with dimension: height = 6 and base = 9

The height is calculated as:

Height = 12ft - 6ft = 6ft

And the base is:

Base = 18ft - 9ft = 9ft

So, the area is:

B = 0.5 * 6ft * 9ft

B = 27ft^2

Part C is a triangle with dimension: height = 7 and base = 7

So, the area is:

C = 0.5 * 7 * 7ft^2

C = 24.5ft^2

Total Area is:

Area = A + B + C

Area = 108ft^2 + 27ft^2 + 24.5ft^2

Area = 159.50ft^2

If m<1 is the supplement of m<2 and the measure of each angle is given:
svp [43]

Answer:

m<1 = 121°

m<2 = 59°

Step-by-step explanation:

If m<1 is the supplement of m<2 and the measure of each angle is given:

m<1=2x+65

m<2=3x-25

Find m<1:

When two angles are supplement of each other, there sum is equal to 180°

i.e m<1 + m<2 = 180°

Putting values and finding angle 1

2x+65+3x-25=180\\5x+40=180\\5x=180-40\\5x=140\\x=\frac{140}{5}\\x=28

So, we get x=28

Now finding m<1 by putting x=28

m

Now, finding m<2 by putting x=28

m

So, we get:

m<1 = 121°

m<2 = 59°
