Answer:
Scalene and obtuse
Step-by-step explanation:
The triangle is scalene because all the sides are not equal, and it is obtuse because the central angle is greater than 90 degrees.
The system of linear equations that relates x and y:
x= 15 + y
5 x = 2 y+ 525
We will solve this system using substitution method:
5(15 + y)=2 y + 525
75 + 5 y = 2 y + 525
5 y - 2 y = 525 - 75
3 y = 450, y = 450 : 3 y = 150
x = 15 + y x = 15 + 150 x = 165
