Two rectangles are similar. The first is 6 inches wide and 4 inches long. The
second is 9 inches wide. Find the length of the second rectangle.
Answers
Answer:
It is 6 inches long
Step-by-step explanation:
Since they are similar the ratio of width and length will be the same for both so the ratio for the first one is 2/3 so whats two thirds of 9? 6, and that's your answer. If you have any questions about this just leave a comment

Find the interior angle sum of this polygon.
Can someone help????
Answers
===================================================
Explanation:
See the diagram below. It shows there are 10 sides, so n = 10.
We'll plug this value of n into the formula below to find the sum of all ten interior angles
S = sum of interior angles
S = 180(n-2)
S = 180(10-2)
S = 180(8)
S = 1440 degrees
---------------
A different approach:
Let's assume this polygon is a regular polygon. This means each angle is congruent to one another.
We have n = 10 sides, so each exterior angle is E = 360/n = 360/10 = 36 degrees.
Each interior angle adjacent to this 36 degree exterior angle is
180-E = 180-36 = 144 degrees
Since we have 10 equal angles of 144 degrees each, so overall the interior angles add to 10*144 = 1440 degrees
Side note: if this polygon is not a regular polygon, then this section does not apply. You would use the first method instead.

for all positive angles less than 360°, if csc csc (2x+30°)=cos cos (3y-15°), the sum of x and y is?
Answers
Answer:
35 degrees
Step-by-step explanation:
for all positive angles less than 360°, if csc (2x+30°)= cos (3y-15°), the sum of x and y is?
Let the given expression be equal to 1, hence;
csc (2x+30°)= cos (3y-15°) = 1
csc (2x+30°) = 1
1/sin(2x+30) = 1
1 = sin(2x+30)
sin(2x+30) = 1
2x+30 = arcsin(1)
2x+30 = 90
2x = 90-30
2x = 60
x = 60/2
x = 30 degrees
Get the value of y;
cos (3y-15°) = 1
3y - 15 = arccos (1)
3y - 15= 0
3y = 0+15
3y = 15
y = 15/3
y = 5
Sum of x and y;
x+y = 30 + 5
x+y = 35degrees
Hence the sum of x and y is 35 degrees

5 + 4x = -11
Answers
Answer:
x=-4
Step-by-step explanation:
5+4x=-11
4x=-11-5
4x=-16
x=-16/4
x=-4
5+4(-4)=-11
5-16=-11
-11=-11
Answer:
x = -4
Step-by-step explanation:
5 + 4x = -11
4x = -11 - 5
4x = -16 (Divide 4 both sides)
x = -4
5 + 4x = -11
5 + 4(-4) = -11
5 - 16 = -11
-11 = -11
