Answer:

1st: 116°

2nd: 64°

Step-by-step explanation:

Supplementary angles add up to 180 degrees. We can make the first supplementary angle be represented by: 2x - 12 and the second supp. angle be represented by x.

Make both of these expressions add up to 180.

(2x - 12) + (x) = 180

Combine like terms.

3x - 12 = 180

Add 12 to both sides.

3x = 192

Divide both sides by 3.

x = 64

Substitute 64 for x into the first supp. angle's expression.

2(64) - 12 = 116

The first supp. angle is 116 degrees and the second is 64 degrees.

Hi

I belive you add the top side (4) plus the bottom side (9.5) witch would equal 13.5 times the hieght (3) equals 40.5 divided by 2 equals 20.25. the area is 20.25ft squared

another way to do it
4+9.5= 13.5
13.5×3= 40.5
40.5÷2= 20.25ft

Answer:

18 and 20, 4

Step-by-step explanation:

Math reasoning 1:

Set the first number as x and the other one as x+2 because it is a consecutive even number.

x+x+2=38

2x=36

x=18

18+2=20

The 2 consecutive numbers are 18 and 20

Problem solving 1:

Write out equation first, set the unknown number as x

5+x=9

x=4

the number m and 5/8 are additive inverses.drag and drop m to their correct positions on the number line.drag and drop the label
monitta

The additive inverse of a number is that number with its sign changed.

The additive inverse of 5/8 is -5/8, so that is the value of <em>m</em>.

The sum of a number and its additive inverse is <em>zero</em>. (This is actually the definition of <em>additive inverse</em>.)

5/8 is found at 5/8 on the number line.

m is found at -5/8 on the number line.

"sum" is found at 0 on the number line.
