5 0

Answer:

20 sides.

Step-by-step explanation:

The exterior angle = 180 - 162 = 18 degrees.

Since the sum of the exterior angles = 360 degrees the number of sides

= 360 / 18

= 20 sides.

<h3>Answer: 104 degrees</h3>

================================

Work Shown:

Inscribed angle theorem

arc measure = 2*(inscribed angle)

arc BCD = 2*(angle A)

arc BCD = 2*(97)

arc BCD = 194 degrees

-------------

Break arc BCD into its smaller pieces

arc BCD = (minor arc BC) + (minor arc CD)

194 = (90) + (minor arc CD)

194-90 = minor arc CD

104 = minor arc CD

<h3>minor arc CD = 104 degrees</h3>

Hep me on this please
Alona [7]

Answer:

The answer is 2240m².

Step-by-step explanation:

Given that the formula of area of trapezium is A = 1/2×(a+b)×h where a and b represents the length and h is height :

area =  \frac{1}{2}  \times (a + b) \times h

let \: a = 50 \\ let \: b = 90 \\ let \: h = 32

area =  \frac{1}{2}  \times (50 + 90) \times 32

area =  \frac{1}{2}  \times 140 \times 32

area = 70 \times 32

area = 2240 \:  {m}^{2}
