Answer:

see below

Step-by-step explanation:

The ASA congruence postulate is being invoked, so you're looking to show two angles and the side between them are congruent.

_____

Personally, I'd go at it differently. I'd say that alternate interior angles ∠C≅∠E means AE║CD, so ∠A≅∠D because they're alternate interior angles. B does not need to be a midpoint for this proof.

Step-by-step explanation:

$16=2^4\\\\8=2^3\\\\16^{2n-3}=8^{4n}\\\\(2^4)^{2n-3}=(2^3)^{4n}\qquad\txt{use}\ (a^n)^m=a^{nm}\\\\2^{(4)(2n-3)}=2^{(3)(4n)}\iff4(2n-3)=12n\qquad\text{use the distributive property}\\\\(4)(2n)+(4)(-3)=12n\\\\8n-12=12n\qquad\text{subtract}\ 8n\ \text{from both sides}\\\\-12=4n\qquad\text{divide both sides by 4}\\\\\dfrac{-12}{4}=\dfrac{4n}{4}\\\\-3=n\to n=-3$

384 in^{3}. because if you have to add the bases together then so 7+5=12 then you times the width and height together so 4*8=32. Then you times 12 * 32 = 384.

What 2 numbers add to -3 and multiply to 2

serg [7]

We need to look at factors of 2, which are only 2 and 1... How do we get them to add to -3? Well, they have to be negative.

-2 + -1 = -3

What about the multiplication? A negative × a negative = a positive, so

-2 × -1 = 2

So your answer is

-2 and -1

Find the measure of angle 1

nikklg [1K]

Answer:

Angle 1, 2, 4 = 45 degrees

Step-by-step explanation:

2x+15 = x+30

-15 both sides

2x = x+15

-x both sides

x = 15

Plug x = 15 into x+30 or 2x+15

15+30 = 45

2(15)+15 = 45
