The sum of the interior angles in a triangle = 180

There are three angles, 30, x, and x.
Since there are two x, you can therefore write this equation and solve for x.

180 = 2x + 30
150 = 2x
/2 /2
75 = x

Therefore the answer is C, 75.

Well since both of the angles are congruent we just need to do 180 - 30 = 150
150 / 2 = 75

(C) is the answer :D

The way to write this expression in mathematics is A'∩B

<h3>How to solve for the expression</h3>

In order to get the right way to write this expression we have to break it down in two parts.

First we are told that some of the elements are not in A.

This is represented as A'.

Then we are told that they are in the set B. Hence we have it written as B.

Then the expression not in set A but are in set B would be written as

A'∩B.

Pocahontas opens a savings account with $640 dollars that earns 3.9% interest per year not compounded. How much money to the nea

solmaris [256]

Given:

Principal value = $640

Rate of interest = 3.9% not compounded

Number of years = 8

To find:

The amount after 8 years.

Solution:

It is given that the interest is not compounded. It means, we need to find simple interest.

Formula for simple interest:

$I=P\times r\times t$

where, P is principal, r is rate of interest and t is time in years.

Put P=640, r=0.039 and t=8.

$I=640\times 0.039\times 8$

$I=199.68$

So, the interest is $199.68.

Now, amount after 8 years is

$A=P+I$

where, P is principal and I is interest.

$A=640+199.68$

$A=839.68$

Therefore, the amount after 8 years is $839.68.
