Answer:

x = 108°

Step-by-step explanation:

In a trapezoid, each lower base angle is supplementary to the upper base angle on the same side.

72° is a lower base angle and x the upper base angle on the same side, hence

x + 72 = 180 ( supplementary angles sum to 180° )

subtract 72 from both sides, thus

x = 108°

The circumference of the hub cap of a tire is 82.14 centimeters. Find the area of this hub cap. Use 3.14 for pi

earnstyle [38]

Answer:

Circumference = 2 * radius * 3.14

82.14 = 2*3.14 r

r= 82.14/6.28=13.079 cm.

So the area = 3.14 r^2

3.14*13.079^2

537.129 cm ^2

Hope this helps :)

A line is parallel to y = -2x + 1 and intersects the point (4, 1). What is the equation of this parallel line?

Furkat [3]

Using the point slope form y - y1 = m(x-x1)

m is the slope, because the lines are parallel the slope is identical, so m = -2.

Replace x1 and y1 with the given point and then solve for y:

y - 1 = -2(x-4)

Simplify:

y - 1 = -2x + 8

Add 1 to both sides:

y = -2x +9

4x^2 - 24x + 7 = 3<br> I don't understand how to get to the final answer of <br> x= 3 ± 2sqrt2

sergey [27]

4x² - 24x +7-3 =0
4x² - 24x + 4=0 /:4
x² - 6x +1=0
Use formula

$x = \frac{-b+/- \sqrt{ b^{2}-4ac } }{2a} 

For our equation a=1, b= - 6, c = 1

x= (6+/- \sqrt{36-4)}/2 = \frac{-6+/- \sqrt{32} }{2} = \frac{-6+/- \sqrt{16*2} }{2} = \frac{-6+/-4 \sqrt{2} }{2} 

= -3 +/- 2\sqrt{2}

Does the point (7, 4) satisfy the equation y = x − 3?

CaHeK987 [17]

Answer:

Yes.

Step-by-step explanation:

If we wrote the equation down

7=4-(-3)

Then, we do keep, change, change

7 = 4+3

Y = 7

The equation is true, so that means the points are.
