Answers

Answer 1

Answer:

Answer:

1. Sqaure 2. Equialteral Triangle 3. Each angle is 108°

Step-by-step explanation:

Before we go ahead with this problem let us see the sum of all internal angles in various polygons.

a) Triangle : 180

b) Quadrilateral : 360

c) Pentagon : 540

d) Hexagon : 720

Now let us do each part

Part 1.

Polygon sum is 360° , hence it is a quadrilateral . And each angle measures 90° , Hence it is either a square or a rectangle . Hence our answer from options is square

Part 2,

Measure of each angle of polygon is 60°.

60°*3= 180°

60°*4=240°

60°*5=300°

None of the above gives you a polygon except first . Hence our answer is an triangle and as every angle is equal is an equilateral triangle.

Part 3,

A regular pentagon has sum of its all interior angles is 720°. Total nos. of angle is 5 . Hence measurement of each angle will be

$(720)/(5)=108$

Hence option b is right

Answer 2

Answer: 1. Square.

2. Equilateral Triangle

3. Fact 1 (Each angle measure is 108°)

The formula f=9/5c + 32 is used to convert Celsius to Fahrenheit temperature.If the temperature is 20°C, what is it in Fahrenheit?

28.8°F
43.1°F
68.0°F
93.6°F

Answers

For the answer to the question above asking If the temperature is 20°C, what is it in FahrenheitF=9/5C +32?

Substitute for C = 20
F = 9*20 / 5 + 32
F = 180 / 5 + 32
F = 36 + 32
F = 68
