5 0

<u>Given:</u>

A triangle with a base length of 22 ft and a height of 20 ft.

<u>To find:</u>

The area of the given triangle.

<u>Solution:</u>

The area of a triangle is obtained by multiplying \frac{1}{2} with its base length and its height.

The area of a triangle = \frac{1}{2} (b)(h).

The height is the distance from the base to the highest point on the triangle and the length of the base is the base length.

The given triangle has a base length of 22 ft and a height of 20 ft.

The area of the triangle = \frac{1}{2} (b)(h) = \frac{1}{2} (22)(20).

\frac{1}{2} (22)(20) = \frac{1}{2} (440) = 220 ft².

The given triangle has an area of 220 ft².

What is the area of the shaded region of the circle?
eduard

Answer:

12π ft², B

Step-by-step explanation:

Area of circle: radius²π

The area of the entire circle would thus be 6²π, or 36π

Note that a circle has a total degree measure of 360°, and the shaded area is 120°. Thus, the area of the shaded region would be 120/360 of the circle's area, or 1/3.

1/3 * total area of the circle = area of the shaded region

1/3 * 36π = 12π

Thus, the answer is 12π ft², or B.

65+ 6x + 3x + 9 + 65=180
Ierofanga [76]
Let's solve your equation step-by-step.<span><span><span><span><span>65+6x</span>+3x</span>+9</span>+65</span>=180
</span>
Step 1: Simplify both sides of the equation.<span><span><span><span><span>65+6x</span>+3x</span>+9</span>+65</span>=180
</span><span><span><span>(<span>6x+3x</span>)</span>+<span>(<span>65+9+65</span>)</span></span>=180 </span>(Combine Like Terms)
<span><span><span>
9x</span>+139</span>=180</span><span><span>9x+139</span>=180
</span>
Step 2: Subtract 139 from both sides.
<span><span><span><span>
9x</span>+139</span>−139</span>=180−139</span><span>9x=41
</span>
Step 3: Divide both sides by 9.
<span><span>9x/9</span>=<span>41/9
</span></span><span> x=<span>41/9
 And finally you divided by 41/9 
Answer is x= 4.555556

What is the measure of angle 1?<br> 20°<br> 42°<br> 138°<br> 160°
nikdorinn [45]

Step-by-step explanation:

line s || line t

r is the transversal,

Therefore,

(7x-2)°= (6x+18)° {exterior alternate angles}

7x-6x=18+2

x=20°

r is also a straight line,

therefore,

7x-2+angle1=180° (straight angle)

7x-2+ angle1=180°

7(20)-2+ angle 1= 180°

140°-2+ angle 1= 180°

angle 1= (180-140+2 )°= 42°

angle 1= 42°
