Answer:
m=2
Step-by-step explanation:
(−2,−3);(3,7)
(x1,y1)=(−2,−3)
(x2,y2)=(3,7)
Use the slope formula:
m=y2−y1/x2−x1
=7 − −3/3 − −2
=10/5
=2
Graph:
(-2,-3) is blue
(3,7) is red
In the parallelogram ABCD, M angle A =2x +50 and m angle C= 3x + 40. The measure of ZA is

Answer:
∠A = 70°
Step-by-step explanation:
I'm... guessing this is what you mean? It would've been helpful if you'd provided pictures.
Since all parallelograms consist of two pairs of vertically opposite angles, ∠A and ∠C are equivalent.
Which means that 2x + 50 = 3x + 40.
In which you solve the equation.
2x + 50 = 3x + 40
-2x -2x
50 = x + 40
-40 -40
x = 10
Now, to find ∠A, substitute x into the equation:
∠A = 2x + 50
x = 10
∠A = 20 + 50
∠A = 70
Hence, ∠A = 70°
