$a^{-n}=\left(\frac{1}{a}\right)^n\\\\10^{-7}=\left(\dfrac{1}{10}\right)^7=\dfrac{1}{10,000,000}=0.0000001\\\\2.93\times10^{-7}=2.93\times0.0000001=\boxed{0.000000293}$

Find the value of x<br> A.25<br> B.85<br> C.75<br> D.105

Masteriza [31]

Answer:

The value of x is 75

Step-by-step explanation:

First we need to find the other angle that doesn't have a number in it.

To find the degrees of the other angle we subtract 155 from 180.

180 - 155 = 25

Now we have to find the value of x. Add 80 and 25 together to get 105. A triangle is going to be 180 degrees. Subtract 105 from 180.

180 - 105 = 75

Now we will add 80, 25, and 75 to check our work.

80+25+75 = 180
