4) Here both smaller and larger triangle is "isosceles" in nature.
So, sum would be 180 with two equal sides.
66 + BDE + BED = 180
2 BDE = 180 - 66
BDE = 114 / 2
BDE = 57

In short, Every four angles would be equal to 57

5) A) 7
It is because it must be smaller than the longest side which is equal to 8

6) D) Yes, Because ∠C is congruent to ∠BED

Hope this helps!

Hello!

$7d + 12 -4d -3\\$

Explanation:

↓↓↓↓↓↓↓↓↓↓↓

First this problem it should be the group like terms.

$7d-4d+12-3$

Then you add similar elements.

$7d-4d=3d$

$3d+12-3$

You can also add or subtract by the numbers.

$12-3=9$

$=3d+9$

Answer⇒⇒⇒3d+9

Hope this helps!

Please choose answer choice a,b,c or d

Answer:

A. -4

Step-by-step explanation:

Slope is rise over run, or y2-y1 / x2-x1.

$\frac{y2-y1}{x2-x1} = \frac{-4-8}{2--1} =\frac{-12}{3} = -4$

The slope is A. -4.

Let's see--does that make sense? A slope of four would be pretty steep, and that matches the graph. It also should be negative because the line goes down and to the right, not up and to the right, so -4 makes sense!
