Answer:

  x = 19

Step-by-step explanation:

Assuming all angle measures are in degrees, the sum of them is 180:

  (3x +16) +(4x -15) +(2x +8) = 180

  9x +9 = 180 . . . . collect terms

  x + 1 = 20 . . . . . . divide by 9

  x = 19 . . . . . . . . . .subtract 1

The value of x is 19.

Find the length of side c of a triangle if side a = 15 and side b = 20. A. 25 B. 17.5 C. 20 D. 15
likoan [24]

If one side of a triangle is 15 and another side is 20, then the third side
can be any length between 5 and 35. There are an infinite number of
possible triangles.

IF it happens to be a RIGHT triangle AND side 'a' and side 'b' happen
to be its legs, then the length of the third side is 25.  But you didn't
mention any of those details.

Brainleiest What is the unit rate for 692.08 ft in 21.1 s? Enter your answer, as a decimal, in the box. ft/s
ale4655 [162]

Answer:

Unit rate is 32.9561 feet per second.

Step-by-step explanation:

Unit rate is a number where one quantity is represented so that the other quantity is 1.

So we can give the unit rate of this as number of feet per 1 second.

It has traveled 692.08 ft in 21.1 seconds.

We have to find how many feet it travels in 1 second.

Unit rate = Number of feet / Number of seconds

=\frac{692.08feet}{21.1seconds}

=32.9561 feet per second

A parabola has vertex (2, 3) and contains the point (0, 0). find an equation that represents this parabola.
AfilCa [17]
First write it in vertex form :-

y= a(x - 2)^2 + 3    where a is some constant.

We can find the value of a  by substituting the point (0.0) into the equation:-

0  = a((-2)^2 + 3

4a = -3

a = -3/4

so our equation becomes  y =  (-3/4)(x - 2)^2 + 3
