If triangle ABC, m B = 90°, cos(9 = 17, and AB = 16 units. Based on this information, m Note that the angle measures are rounded to the nearest degree.
units.

m∠A = 62°

m∠C = 28°

AC = 17 units

Step-by-step explanation:

In the given triangle ABC,

m∠B = 90°, Cos(C) = and AB = 16 units

Since, Cos(C) =

Cos(C) =

m∠C = 28.07°

m∠C ≈ 28°

Therefore, side BC = 15 units and AC = 17 units

Now we apply Sine rule in the given triangle.

Sin(A) =

         =

         =

A =

A = 61.93°

m∠A = 62°

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

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

it is c!
