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

H=vt+1/2gt^2 solving for G <br>GIVING BRAINLISEST
ololo11 [35]

Answer:

g=\frac{2h}{t^2}-\frac{2v}{t}

Step-by-step explanation:

So we have the equation:

h=vt+\frac{1}{2}gt^2

And we want to solve for g.

First, isolate g. To do so, subtract vt from both sides:

h-vt=\frac{1}{2}gt^2

Multiply both sides by 2:

2h-2vt=gt^2

Now, divide both sides by t^2:

g=\frac{2h-2vt}{t^2}

Expand:

g=\frac{2h}{t^2}-\frac{2vt}{t^2}

Simplify the second term:

g=\frac{2h}{t^2}-\frac{2v}{t}

And we're done!

The answer to the problem i asked
guapka [62]
8(4x+5)=136
Multiply the number outside of the parenthesis(8) with the numbers inside the parenthesis(4x and 5).
32x+40=136
Subtract 40 from both sides
32x=96
Divide both sides by 32 so the only thing remaining on the side of the variable is only the variable itself.
Final Answer: x= 3
