Answer:

C. right angle

Step-by-step explanation:

when they're shaped like L they're right angles which are always 90 degrees:)

straight angles look like flat lines _ and are always 180 degrees

obtuse angles are bigger than an L shape (more than 90 degrees) but smaller than flat line shapes (less than 180 degrees)

acute angles are smaller than L shapes < (less than 90 degrees)

2. what value of b makes the following equation true

Svetradugi [14.3K]

Answer:

2. 10

3. D. 1 for all n

Step-by-step explanation:

2. The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

a^b = 1/a^-b

$\dfrac{4^8}{(4^2)^{-3}}\div 4^4=\dfrac{4^8}{4^{-6}\cdot4^4}=\dfrac{4^8}{4^{-2}}\\\\=4^8\cdot4^2=4^{10}$

The value of n is 10.

3. Using the above rules of exponents, the expression simplifies to ...

6^(-n+n) = 6^0 = 1

The value is 1 for any n.
