6 0

Answer:

30°

Step-by-step explanation:

x= angle

Supplement: 180-x

Complement: 90-x

180-x + 90-x = 210

270 -2x=210

-2x= 210 -270

-2x= -60

x= 30

Which explains how to show that
alexgriva [62]

Answer:

  c.  Substitute

Step-by-step explanation:

A graph of the function on the left shows the parabola touches the x-axis at x = -8/3. That is, the vertex is on the x-axis. It crosses the y-axis at y = 64.

<h3>Show a value is a root</h3>

A given solution to an equation can be verified by substituting that value into the equation an showing the result is a <em>true statement</em>. Here, the value x=-8/3 is a root of the given equation because that value makes the equation true.

  9\left(-\dfrac{8}{3}\right)^2+48\left(-\dfrac{8}{3}\right)+64=0\\\\9\left(\dfrac{64}{9}\right)-\left(\dfrac{48\cdot8}{3}\right)+64=0\\\\64-\dfrac{3\cdot2\cdot8\cdot8}{3}+64=0\\\\64-2\cdot64+64=0\\\\0=0\qquad\text{True}

Arthur ran around a circular field 3 times. If he ran a total of 750m what is diameter and radius
Dmitrij [34]

Answer:

Hope this helped

Step-by-step explanation:

Circumference = 750 m / 3

Circumference 250 m

Circumference = pi * D where pi = 3.1415926 and D is the diameter in meters

Solving for the diameter

250 m = pi * D

D = 250 m / pi

D = 79.58 m is the diameter of the circular field

Solving for the radius

r = 1/2 D where r is the radius of the circular field

r = 39.59 m is the radius of the circular field

Someone help pleaseee
Doss [256]

Answer:

38°

Step-by-step explanation:

All triangles have a sum of 180°

180 - (119 + 23) = missing angle

180 - (142) = missing angle

38 = missing angle

So, the missing angle has a measurement of 38°
