What is m∠s? enter your answer in the box. __° an isosceles triangle with vertices labeled r, s, and t. side r t is the base. sides r s and side s t are equal. angle r is labeled as 3 x degrees, angle s is labeled as 2 x degrees, and angle t is labeled as 3 x degrees.

∠S = 45°

Step-by-step explanation:

As given in the question, ∠R = 3x ; ∠S=2x ; ∠T=3x

So by using angle sum property of a triangle that sum of all the angles of a triangle is 180°.

We get, ∠R+∠S+∠T =   180

So, ∠S=2x

∠S=

∠S=45°

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.
