Answer:
Step-by-step explanation:
These problems are based on triangle ratios. You cannot use the Pythagorean theorem to solve them.
The first triangle is a 45 45 90 degree triangle (I'm talking about the angles), and so, the ratio is 1:1:
, so I have to divide the hypotenuse by to get the legs. The hypotenuse is 15
, so that divided by is 15
. X is the same length as y because of the triangle ratio, so both x and y for the first triangle are 15.
The second triangle is a 30 60 90 degree triangle, so the ratio is x:x
:2x. The short leg is 7, so 7 * 2 is the hypotenuse, which is 14. The long leg is 7 * , which is 21. So, x for the second triangle is 14, and y for the second triangle is 21.

Answer:
The cross product property
Step-by-step explanation:
The cross product property also known as cross multiplication is a method in math that is most of the time used in solving problems involving ratios usually in a big X form across the equal sign between two ratios.
It is done by multiplying the numerator of the left ratio by the denominator of the right with an equal to the multiplication of the numerator of the right ratio by the denominator of the left.
