A.)23
B.)60
C.)53
D.)30

ABC = 30

Step-by-step explanation:

The two angles are complementary so they add to 90 degrees

2x+14  + x+7  = 90

Combine like terms

3x+21 = 90

Subtract 21 from each side

3x+21-21 = 90-21

3x = 69

Divide by 3

3x/3 = 69/3

x = 23

ABC = x+7 = 23+7 = 30

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
