The perimeter of a pentagon is 48. one side is equal to x, two sides are twice x and two sides are three more than x. what are the measurements of the sides?

  side lengths are 6, 12, 12, 9, 9

Step-by-step explanation:

The perimeter is the sum of the lengths of the sides:

  x + 2x + 2x + (x+3) + (x+3) = 48

  7x +6 = 48 . . . . collect terms

  7x = 42 . . . . . . .subtract 6

  x = 6 . . . . . . . . . divide by 7

Substitute this value into the expressions for the side lengths:

  x = 6

  2x = 12

  x+3 = 9

The side lengths are 6, 12, 12, 9, 9.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
