Answer:
can u please add the statements.
Step-by-step explanation:
<u>Given</u>:
Given that the figure of similar triangles.
The altitude of the triangle is x.
The length of the left part is 30.
The length of the right part is 15.
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the geometric mean theorem.
Thus, we have;

Substituting the values, we have;

Cross multiplying, we get;


Taking square root on both sides, we have;

Thus, the value of x is 15√2
First, divide the shape into two figures ( a semicircle and a rectangle)
Then, find the are or the two shapes using the area formula for a semicircle (

) and the are formula for a rectangle (base x height)
Finally, add the two areas together and you have your answer
Answer:
Step-by-step explanation:
If Amy received 250 dollars for her bday, but she borrowed before 130,
she will have left:
250-130=120 dollars
Solution:
Given, x=-3, y=6, and z=4
Putting these values in the given equation:
-15+(-x)+y
= -15+(-(-3)+6
= -15+3+6
= -15+9
= -6
