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.
