<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
Answer:
Step-by-step explanation:
4+3+5= 12 marbles
3/12 * 2/11 = 6/132 = 4.5%
5000 pounds is equal to 2.5 tons because 1 ton is equal to 2000 pounds
Step-by-step explanation:
first you have to do the subtraction in the parentheses so it's 8+3(4) and then you multiply the 3 by 4 (only the 3 because the 8 isn't next to the multiply) and then you have 12, add 8 and it's 20
90 - (90 × .7) = $27
hope this helps
