If a triangle has three unequal sides, what is true about the angles of the triangle?
A.
One angle must be a right angle.
B.
Two angles must be 45-degree angles.
C.
All three angles must be unequal.
D.
All three angles must be equal.

Bro lemme tell you the real answer

Step-by-step explanation:

The answer is C and I actually have proof.  You said that the triangle has 3 unequal sides.  This means that it is a scalene triangle.  Scalene triangles do not have any equal angles

Still dont believe me?

Heres a picture

In the picture the sides are unequal.  The angles are therefore unequal

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
