Answer:
a=8
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 +15^2 = 17^2
a^2 +225 = 289
Subtract 225 from each side
a^2 +225-225=289-225
a^2 = 64
Take the square root of each side
sqrt(a^2) = sqrt(64)
a = 8

Answer:
The measure of angle x is 50 degrees
Step-by-step explanation:
we know that
----> equation A
----> equation B
solve the system by substitution
substitute equation B in equation A
solve for y
Find the measure of angle x
therefore
The measure of angle x is 50 degrees
