Find the measure of 1 2 and 3 plz

Answers

Answer 1

Answer:

Answer: 1 = 69°, 2 = 69°, 3 = 111°

Step-by-step explanation:

The image is that of an isosceles trapezoid. Which means:

The base angles (1 & 2) are congruent (equal)
which results in the other set of base angles (3 and 111°) being congruent.
Since it is a quadrilateral (4 sides), the sum of the angles is 360°

∠3 = 111° → refer to #2 above.

Let ∠1 =x, then ∠2 = x → refer to #1 above

2(111) + 2(x) = 360 → refer to #3 above

222 + 2x = 360

2x = 138

x = 69

What is the volume of a sphere with a diameter of 14 centimeters? Use 3.14 for pi. Round your answer to the nearest hundredth.A 1077.02 cm3
B 1436.03 cm3
C 1975.43 cm3
D 11,494.04 cm3

Answers

Answer:

Step-by-step explanation:

Answer:

B. 1436.03 cm^3

Step-by-step explanation:

What you do is use the formula of the volume of a sphere which is

v=4/3*3.14*r^3.

The r represents radius and the radius is 7 which is half the diameter.

So you will plug 7 into the formula.

V=4/3*3.14*7^3.

V=1436.03 cm^3 which is your answer.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Robert slices a large loaf of bread to make 12 sandwiches. He made 3 turkey sandwiches and 5 veggie sandwiches. The portion of the ham sandwich will be calculated as below:-

Total sandwich = Turkish sandwich + veggie sandwiches + ham

12 = 5 + 3 + ham

ham = 12 - 8 = 4

Therefore, the fraction of the ham sandwich will be 4.

carter drank 15.75 gallons of water in 4 weeks.he drank the same amount of water each day.about how many days altogether will it take him to drink 20 gallons?

Answers

To answer this first lets see how many gallons of water he drinks per week.

15.75 ÷ 4 = 3.9375

Now lets divide to see how much he drinks each day.

3.9375 ÷ 7 = 0.5625

20 ÷ 0.5625 = 35.5555...

So, it will take Carter about 35 and a half days to finish 20 gallons.

ALGEBRA! NEED HELP!~A glass prism on a chandelier is 75 millimeters long. A base of the prism is an equilateral triangle with side lengtsh of 9 millimeters and a height of about 7.8 millimeters. What is the approximate surface area of the prism?

Answers

To find out a glass prism's surface are you should first find the, base's are. Since the base is triangle, it's are formula is : $A\quad =\quad \frac { h.b }{ 2 }$ (which h is height and b is base length). $A\quad =\quad \frac { 7,8.9 }{ 2 } \n A=\quad \frac { 70,2 }{ 2 } \n A=\quad 35,1$ since there are two triangle's their total area will be 70.2 To find the remaining surface's are multiply the perimeter of the base with the length. $perimeter\quad =\quad 9\cdot 3=27\n 27\cdot 75=2025$ then sum the total surface : 70,2 + 2025 = 2095,2
