The exterior angles sum to 360º. Let x be the measure of each exterior angle. Then

45x = 360º ==> x = 8º

Then each interior angle (which is supplementary to an exterior angle) has measure (180 - x)º, so they have measure 172º.

Answer:

The equivalent expression $\frac{8^4}{7^4} = \frac{4096}{2401}\approx 1.71$

Step-by-step explanation:

Given:

$(\frac{8}{7})^4$

We need to find the equivalent for given expression.

Solution:

$(\frac{8}{7})^4$

Now by using Law of indices which states;

$(\frac{a}{b})^n= \frac{a^n}{b^n}$

So applying the same in given expression we get;

$\frac{8^4}{7^4}$

Now we can say that;

$8^4 = 8 \times 8 \times 8 \times 8$

Also

$7^4 = 7 \times 7 \times 7 \times 7$

$\frac{8^4}{7^4} = \frac{8 \times 8 \times 8 \times 8}{7 \times 7 \times 7 \times 7}$

Now We know that;

$8 \times 8 \times 8 \times 8 = 4096$

$7 \times 7 \times 7 \times 7 = 2401$

On substituting we get;

$\frac{8^4}{7^4} = \frac{4096}{2401}\approx 1.71$

Hence The equivalent expression $\frac{8^4}{7^4} = \frac{4096}{2401}\approx 1.71$

aliina [53]

The answer would be $124.80. The answer would be 124.80 because 96.00x.30 equals 28.8 You then add that to the 96.00 which equals $124.80. Hope this helps!

Rina8888 [55]

Answer:

D) L=50 W=50

Step-by-step explanation:

Just "plug and chug" these numbers and see which doesn't work.

A is not it, 20+30=50 (then *2 because we need 4 sides not just 2) 50*2=100

B isn't it, 10+40=50*2=100

C ain't it either 49+1=50*2=100

D is the answer 50+50=100*2=200
