Answer:

x=62

Step-by-step explanation:

The interior angles of a triangle must add up to 180 degrees.

Therefore, the three angles inside of this triangle should equal 180 degrees when added together.

x+68.5+49.5=180

Combine like terms by adding 68.5 and 49.5

x+(68.5+49.5)=180

x+118=180

We want to find the value of x. Therefore, we must get x by itself.

We should perform the inverse operation to both sides. 118 is being added to x. The inverse of addition is subtraction. Subtract 118 from both sides.

x+118-118=180-118

x=180-118

x=62

x is 62 degrees.

Three people split an amount of money. 1 268 dollars and 1 gets 200 dollars. The third gets 40 percent. What is the amount?

Maksim231197 [3]

The total amount is $ 780

<em><u>Solution:</u></em>

Let the total amount be "x"

Given that,

First person gets $ 268

Second person gets $ 200

Third person gets 40 %

This means, third person gets 40 % of total amount

Third person = 40 % of x

$Third\ person = 40 \% \times x\\\\Third\ person = \frac{40}{100} \times x\\\\Third\ person = 0.4x$

We know that, total amount is equal to sum of amount got by all three persons

Total amount = first person + second person + third perosn

$x = 268 + 200+ 0.4x\\\\x - 0.4x = 268 + 200\\\\0.6x = 468\\\\x = \frac{468}{0.6}\\\\x = 780$

Thus the total amount is $ 780
