Answer: C.... 42+x=90

Why: Because angle A is known as 42degrees while x is unknown. So adding angle A and x will equal the angle 90degrees.

Hope this helps!

What is the distance between two points ( 3,-4)(-4,-4)
kirill [66]

Answer:

To find the distance between two points, use the distance formula.

It will be the square root of (x2-x1)squared + (y2-y1)squared.

Use (3,-4) as x1, y1. Use (5,1) as x2, y2.

We get the square root of (5-3)squared + (1- -4)squared.

That gives us the square root of 2 squared + 5 squared.

Now we have the square root of 4 + 25, = the square root of 29.

That is the distance between the two points
