If you divide 16/40, you’ll find that that ratio is 2.5. So then you just multiply 16 x 2.5. You’ll get 18.
18 is the length of the top of the trapezoid.
You set 18=2x+4 and solve it algebraically. Subtract 4 from both sides.
14=2x
Divide by 2 and x=7
(You can also check that the ratio is right by 16/18 is the same decimal value as 40/45. You’ll get .88888...)

What is the area of major sector DFE?
A. 157.86 square cm
B. 133.94 square cm
C. 132.54 square cm
D. 125.57 square cm
Answers
Answer:
Step-by-step explanation:
Area of the circle = πr² = π7.3² = 53.29π
Area of major sector = 53.29π(285/360) ≈ 132.54 cm²
The area of major sector DFE is 132.5 sq.cm , Option C is the right answer.
What is a Major Sector ?The region bounded by the two radii and intercepted arc in a circle is called a sector .
The angle made by the radii to the center of the circle is called central angle .
if the measure of the angle is less than 180 degree then it is called minor sector and if the angle is more than 180 degree , it is called Major Sector.
It is given that
The radii of the circle is 7.3 cm
The angle subtended by the major sector at the center is 285 degree.
The area of the sector is given by
= ([tex]\rm \theta[/tex] / 360) * Area of the circle
Area of the circle is πr²
Area of the sector = ( 285 / 360) * (22/7) * (7.3)²
Area of the sector is 132.5 sq.cm
Therefore , The area of major sector DFE is 132.5 sq.cm , Option C is the right answer.

In triangle UVW, u = 20, v = 47. and w = 60. To find m∠ W,
which law would you use? Laws of Sines or Laws of Cosines? and why?
Answers
Answer:
We would use the Law of Cosines to solve the question.
m∠ W = 121.8°
Step-by-step explanation:
In triangle UVW, u = 20, v = 47. and w = 60. To find m∠ W,
which law would you use?
The Law we would use to find find m∠W is the Law of cosines, this is because in the question above we are given 3 known sides of a triangle and we are asked to find an unknown angle.
Law of cosines when we are to find an unknown angle =
m∠ W = arc cos [u² + v² - w²/ 2uv]
m∠ W = arccos [ 20² + 47² - 60²/ 2 × 20 × 47]
m∠ W = 121.81159°
Approximately = 121.8°
