Find m P. Quadrilateral

Mathematics
1 answer:
Mashutka [201]3 years ago
8 0

Answer:

m∠P = 107º

Step-by-step explanation:

Since two sides are parallel this is a trapezoid

In a trapezoid, the angles on the same leg (called adjacent angles) are supplementary, meaning they add up to 180 degrees.

(7x + 31) + (21x - 19) = 180

combine like terms

28x + 12 = 180

Subtract 12 from both sides

28x = 168

Divide both sidees by 28

x = 6

m∠P = 21x - 19

m∠P = 21(6) - 19

m∠P = 107º

3. What is the value of the expression 5x -2 when = 3/4
yaroslaw [1]

Answer:

Step-by-step explanation:

Pay attention to the procedure:

(5(10)^2)^3/(10(5))^4. What we need is plug in the corresponding x and y values Then you have to do x squared before you multiply it by 5 like this: (5(100))^3/(10(5))^4 Now solve for what is in the top parenthesis. (500)^3/(10(5))^4 500^3=125000000 Now work on the denominator. Do what is inside the parenthesis first 10*5=50 Now (50)^4=6250000 Now divide the numerator and the denominator. 125000000/6250000 Which equals 20, Please check if I'm wrong but I think this is what you need

anthony bought an 8 foot board.He cut off 3/4 of the board to build a shelf,and gave 1/3 of the rest to his brother for an art p
e-lub [12.9K]
Convert your feet to inches.
So 8 times by 12 = 96 inches
if you have 3/4 of the board used. 
3/4= .75 
if you were to times 96 by .75 = 72 inches.
So you used 72 inches and you have 24 inches left

now do 1/3= .33
times .33 by 24= 8
8 inches is how long you would give to Anthony's brother.
