How do I find a missing side of an obtuse triangle when two angles and one side are given? Angle A = 45
Angle B = 30
Side a = 12 cm

Step-by-step explanation:

I think you mean missing angle.

This can be solved by using the triangle sum theorem. It states that the 3 angles of a triangle always add up to 180°. We just have to subtract the other 2 angles from 180°. 180 - (45 + 30) = 180 - 75 = 105.

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
