A. 3

You have to know figure out as many sides as possible before setting up the ratio.

On the short leg the entire leg is equal to 20, and some part of the line is labeled as 12. So you do do 20-12 which would equal to 8. So the shorter part of the short leg equals to 8.

Then you do the long leg. The entire leg equals to 35. Some part of the long leg is labeled as 7x. So you can label the other part of the long leg as 35-7x.

Since you have the numbers for the ratio now, you can do the next steps.

The first step is picking a location and then going any direction.

When I solved it, I started at the top and went down.

8/35-7x=12/7x

Then you cross multiply.

8*7x=56x. 12*35-7x=420-84x

56x=430-84x

Add 84x on both sides

140x=420

Divide 140 in both sides

X=3

a farmer sold 2/5 of his cows and another 10th was stolen he then gave 20% of the cows that was left what percentage of the cows
igor_vitrenko [27]

Answer:

4/5 of the cattle is left

Step-by-step explanation:

Given,

A farmer sells 2/5 of his cattle

Let "x" be the total number of cattle

Then,

sold = 2 / 5 x

Then,

Remaining = x - 2x / 5

remaining = 3x / 5

He gives 1/3 of the remainder to his son

son = 1 / 3 × 3x / 5

son = x / 5

Then,

Remaining = 3x / 5 - x / 5

Remaining = 4x / 5

Hope this answer helps you :)

Have a great day

Mark brainliest

Thus 4/5 of the cattle is left

Find the value of x.
castortr0y [4]

The angle x has a measure of 110 degrees

<h3>How to determine the value of x?</h3>

From the question, we have the triangle shape that can be used in our computation:

On the triangle, the external angles are

x, 140 and 110

These angles are on the same straight line with their corresponding internal angles

By the angle on a straight line theorem, we have the internal angles to be

180 - x, 180 - 140 and 180 - 110

The sum of these angles is 180

So, we have

180 - x + 180 - 140 + 180 - 110 = 180

Evaluate

x = 110

Hence, the value of x is 110 degrees
