Answer:
Step-by-step explanation:
x + y = 40
x>y
(11/2)y - (13/4)*x = - 25
x = 40 - y
(11/2)y - (13/4)(40-y) = - 25 multiply by 4
22y - 13( 40 - y) = - 100
22y - 520 + 13y = -400 Add 520
35y = 120
y = 120 / 35
y = 3 3/7
x = 40 - y
x = 36 4/7
Answer:
obtuse and scalene
Step-by-step explanation:
at least one angle is larger than 90º, and so it's an obtuse angle.
scalene triangle means all sides of the triangle are different lengths.
Idk if I'm right but 4 maybe
