Answer:
A≈422.37
You use the equation A=πr(r+h2+r2) to find the surface area of a cone
I'll focus on problem 19 and problem 22
============================================================
Problem 19
Answers:
-------------------------------
Explanation:
The horizontal lines are parallel. Note the arrow markers along the interior portion of the lines. These similar markers tell us how the lines pair up to be parallel to one another.
Since the horizontal lines are parallel, this means the angles in question are congruent. They are corresponding angles.
x+15 = 102
x = 102-15
x = 87
Which leads to
x+15 = 87+15 = 102
============================================================
Problem 22
Answer: y = 27
-------------------------------
Explanation:
We have a pair of alternate exterior angles. They are congruent due to the parallel lines.
Let's solve for y.
7y-55 = 3y+53
7y - 3y = 53+55
4y = 108
y = 108/4
y = 27
Answer: multiply (1/3√x-3/2√y)^2
Step-by-step explanation: Answer: 1/2 of 1/2 is 1/4.
Well from what i see this equation isn't a point at all, however it does start at (0,0)
Make all a and constant number in different side
10-7=16z-7z+2z
3=11z
z=3/11
