And 5 equals the cost of 5.
Answer:
X = 20

Answer:
r=-3
Step-by-step explanation:
-----(A)
Here we are given that
And the value of m is -2
Replacing them in (A)
Hence the value of r is -3 and the coordinate is(2,-3)
The 3 angles of a triangle will add up to 180 degrees.
5x + 2x + 3 + 3x - 3 = 180...combine like terms
10x = 180
x = 180/10
x = 18
one angle is : 5(x) = 5(18) = 90 degrees
the other angle is : 2x + 3 = 2(18) + 3 = 39 degrees
the last angle : 3x - 3 = 3(18) - 3 = 51 degrees
I just did that one, it's C - isosceles right triangle.
