So we isolate p, to get the answer we do p=101-77, which is 24,
so p=24

In a right triangle the square on the hypotenuse is equal to the sums of the squares on the other two sides.
Answer:
slope = - 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = -
x +
← is in slope- intercept form
with slope m = - 
Answer:
Step-by-step explanation:
To create an augmented matrix, we need to transfer the coefficients of each system of equations into its respective place in the matrix. The first row will be the coefficients of the first equation and so on. The number to the right of the equals sign is the last column of the augmented matrix.

Answer:
71
Step-by-step explanation:
To find the value of x, you must subtract 38 from 180 because all triangles' angles add up to 180. Then, you get 142, so you divide 142 into 2 because the triangles is an isosceles triangle. That's how you get an answer of 71.
