base: b

height: 5b - 2

Area = 1/2 (b) (h)

36 = 1/2(b) (5b - 2)

72 = b(5b - 2)          <em>multiplied both sides by 2 to clear the denominator</em>

72 = 5b² - 2b

0 = 5b² - 2b - 72

Use quadratic formula to find that b = 4 or -3.6 (disregard the negative) so

b = 4

height: 5b - 2  = 5(4) - 2  = 20 - 2  = 18

Answer: base=4 in, height=18 in

h = 5b - 2

\frac 1 2 b h= 36

b(5b - 2) = 72

5b^2 - 2b - 72 = 0

(b - 4)(5b + 18) = 0

b = 4 \textrm{ or }b = -18/5

We can rule out the negative length.

h = 72/b = 72/4 = 18

Answer: b=4, h=18

In the figure, AB | CD and<br>mZ1 = 120°<br>What is mZ5<br>​
Stells [14]

Answer:

Step-by-step explanation:

If AB is parallel to CD and there is a transversal cutting through both (as there is, although it is not named here), then by the definition of corresponding angles, angles 1 and 5 are corresponding and are therefore, congruent. If angle 1 measures 120 then so does angle 5. Learn these...they're very important and are prevalent in triangle stuff in geometry!!!

Is one side of a rectangular fish tank best represented by a point, line, plane, or ray?
Mandarinka [93]
Plane, think of planes as a rectangular shape. Rays and lines are just arrows. And a point is just one single dot

In this circle, the area of sector COD is 50.24 square units.
Bezzdna [24]

Answer:

Radius = 8 units

Length of arc AB = 8.37758 units

Step-by-step explanation:

The sector COD is 1/4 the size of the circle.

the vertex angle is 90° and a circle has 360° at the center.

So the area of sector COD/area of Circle = 90/360 = 1/4

This means the area of the circle is 4 * 50.24 = 200.96 square units

Area of circle = πr² where r is the radius
πr² = 200.96

r² = 200.96/ π = 63.9676 ≅ 64
Therefore r = √64 = 8 units

The circumference of the circle is 2πr = 16π units

arc AB has a vertex angle of 30°.

30°/360° = 1/6

So the length of the arc is 1/6th the circumference of the circle =

(1/6) * 16π  = 2.67π  units or 8.37758 units
