Answer:
A. trapezoid
Step-by-step explanation:
The missing angle U is 86°, the value that makes the total be 360°. Then the top two angles total 180°, as do the bottom two angles. This means sides SV and TU are parallel, but sides UV and ST are not.
The figure has one pair of parallel sides, so is a trapezoid.
__
A concave quadrilateral has a reflex angle. This figure does not.
Answer:
10' 11''
Step-by-step explanation:
131 / 12 = 10.1666...
10 * 12 = 120
131 - 120 = 11
12 represents the feet and the remainder, 11, is the inches.
Answer:
188.5 in.
Step-by-step explanation:
The circumference of a circle is given by:
2πr Where r is the radius, and π is the ratio of the circumference of a circle to its diameter.
We have radius = 30
∴
2(30)π = 60 π
If π ≈ 3.1416
2(30)(3.1416) = 188.5in.
<u>Given</u>:
The radius of the circle is 10 cm
The central angle of the circle is (360 - 90)° = 270°
We need to determine the area of the composite figure.
<u>Area of the composite figure:</u>
The area of the figure can be determined using the area of the sector formula.
Thus, we have;
Substituting and in the above formula, we get;
Simplifying, we get;
Multiplying, we get;
Dividing the terms, we get;
Thus, the area of the composite figure is 235.5 cm²
Hence, Option C is the correct answer.
