Answer:

x=21

Step-by-step explanation:

Notice the right angle. Perpendicular to it on the right, we have two complementary angles, 25, and 3x+2 (you can ignore the parentheses basically). Because they are complementary angles, they will add up to 90, so we can make an equation to solve for x:

25+3x+2=90

3x+2=65

3x=63

x=21

So x=21 is the correct answer. Let me know if you have any questions about my explanation.

What is the midpoint of AB with A(-1, 5) and B(6, -3) A (-4, 3.5) B (1, 2.5) C (2.5, 1) D (3.5, -4)

Alina [70]

Answer:

Option C (2.5, 1) is the right alternative.

Step-by-step explanation:

The given points are:

A = (-1, 5) = (x₁, y₁)

B = (6, -3) = (x₂, y₂)

Now,

The midpoint on X-axis is:

= $\frac{x_1+x_2}{2}$

= $\frac{-1+6}{2}$

= $\frac{5}{2}$

= $2.5$

The midpoint on Y-axis is:

= $\frac{y_1+y_2}{2}$

= $\frac{5+(-3)}{2}$

= $\frac{5-3}{2}$

= $\frac{2}{2}$

= $1$

Thus the midpoint of AB is "2.5, 1".
