Question

Marissa is building a frame for a Sandbox that the borders she has are too short she must join two borders together to build a side are showing at what angle did she cut the first board

Answer 1

x = 125°

Step-by-step explanation:

The first board is the left side of the figure, so:

What do I need to find?

The angle of the first board is the value of x, so we need to find x.

What information do I need to use?

To know the angle of x, we will use the measure of the adjacent angle

How will I use this information?

Since the angles with measures x and 55° form a straight line, the sum of these angles is 180°, so we will write an equation and then solve for x.

Solve the problem

We can write the following equation:

x + 55 = 180

x + 55 - 55 = 180 - 55

x = 125

Therefore, the angle is 1250

How can you check the answer to the problem?

Finally, we can check the answer adding 125 and 55 as:

125 + 55 = 180

Since the sum is 180, the answer is correct.
