What is the midpoints of a segment whose endpoints are (-3, 8) and (7, -2) ?

1 answer:

3 0

$M = (\frac{x_{1} + x_{2}}{2}, \frac{y_{1} + y_{2}}{2})$
$M = (\frac{7 - (-3)}{2}, \frac{-2 + 8}{2})$
$M = (\frac{7 - 3}{2}, \frac{6}{2})$
$M = (\frac{4}{2}, 3)$
$M = (2, 3)$

The perpendicular bisector of side AB of triangle ABC intersects the extension of side AC at D. Find the measure of angle ABC if

Karolina [17]

Answer:

23°

Step-by-step explanation:

Let the interior angles of ΔABC be referenced by A, B, and C. The definition of point D means that ΔDAB is an isosceles triangle, so we have the relations ...

A + B + 118 = 180 . . . . interior angles of ΔABC

A = B +16 . . . . . . . . . . base angles of ΔDAB

Using the expression for A in the second equation to substitute into the first equation, we get ...

(B+16) +B +118 = 180

2B + 134 = 180 . . . . . collect terms

2B = 46 . . . . . . . . . . . subtract 134

B = 23 . . . . . . . . . . . . divide by 2

Double the quotient of 3 and 6

Hitman42 [59]

$\huge{\boxed{1}}$

This statement can be represented as $2*\frac{3}{6}$ , since the quotient is the answer to a division problem.

Divide. $2*\frac{1}{2}$

Multiply. $2*\frac{1}{2}=\frac{2}{1}*\frac{1}{2}=\frac{2*1}{1*2}=\frac{2}{2}$

Simplify. When the numerator and denominator are the same, the fraction is equal to 1. $\frac{2}{2}=1$

What is angle m 2 ? What is angle m 1?

mezya [45]

Answer:

Angle measure two is equal to 75º and Angle measure one is equal to 105º

Step-by-step explanation:

I know this because angle one is alternate exterior angle with angle 7 and angle seven forms a staight line with angle 75 so to find angle 7 you have to do 180-75 and that would equal 105.

for angle two it is interior angles with angle 75 so this means that are congruent angles which means they both have the same measure

How can you use properties of operation to solve problems?

MAXImum [283]

First of all not to be rude, but it is order of operations not properties of operations. Second, you can solve equations by going in the order of PEMDAS or Parentheses, Exponents, Multiplication, division, addition, and subtraction. Multiplication and division are switchable, addition and subtraction. If you do not follow this order you get the equation or inequality wrong.
