Answer:
a) x= 75
b) 105 is the same angle as angle B, I subtracted 180 by 105
180-105= 75
B*H = area of rectangle so do 100/5 to get base so Base=20m
One of the indicies rules is:
![{a}^{ \frac{m}{n} } = \sqrt[n]{ {a}^{m} }](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B%20%5Cfrac%7Bm%7D%7Bn%7D%20%7D%20%20%3D%20%20%5Csqrt%5Bn%5D%7B%20%7Ba%7D%5E%7Bm%7D%20%7D%20)
As you "root the bottom and power the top"
Using this format, we can see that 3rdrt8^x can be written as 8^x/3
By the way, 3rdrt8 means 3rd root of 8
5 × 3.25= 16.25 then 16.25 + 16.25 = $32.50 < thats the answer.
Answer:
2.24
Step-by-step explanation:
If you mean sqrt(5), then the answer is 2.236, which rounds to 2.24
