Answer:
80°
Step-by-step explanation:
The sum of the angles of a triangle is always 180°.
∴ 2x + 3x + 5x = 180°
10x = 180°
x = 180 / 10
x = 18
The biggest angle = 5x
= 5 * 18
= 90°

Answer:
x= 4
Step-by-step explanation:
Answer:
The relationship in this equation is linear, but not proportional. If it was proportional, then replacing x with nx should give ny as the answer. Example:
y = 3x
Replace x with 2x.
y' = 3(2x) = 2(3x) = 2y
y' = 2y
This is proportional. But if you replace x with 2x in
y = 3x + 5,
you will not get 2y for y'. This case is not proportiona
