1 answer:

3 0

Answer:

Points A, B, and Cform a triangle. Complete the statements to prove that the sum of the interior angles of AABC is 180°.

Statement

Reason

Points A, B, and C form a triangle.

given

Let DE be a line passing through B and parallel to AC. definition of parallel lines

23 – 25 and 21 - 24

m21 = m 24 and 23 = m25

m24+ m2 2 + 25 = 180°

mZ1 + Z2 + m23 = 180°

lys-0071 [83]

Answer:

-10

Step-by-step explanation:

9^-8 x 9^-2 = a^b

We know that x^y * x^z = x^(y+z)

9^-8 x 9^-2 = 9^(-8+-2) = 9^(-10)

a= 9

b = -10

What is an equation in point-slope form of the line that

-Dominant- [34]

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

where

m is the slope

( x1 , y1) is the point

From the question the point is (-3, -1) and slope 2

The equation is
