Answer:
The area would be the length of the rectangle times the with of the rectangle.
Step-by-step explanation:
Imagine the rectangle is cut up into tiny squares. For example, if the length of the rectangle is 5, and the with is 6, than each square would represent 1 unit that is in the area of the rectangle. So if you put 6 squares on the length of that rectangle, that side would be filled up, because the with is 6 and the length would be 4. Add 6 more squares on the with and you have 3 more square colluoms. Add 3 more times 6 than the rectangle would be filled with squares. What we just did is finding the area, which can be simplified to making 5 rows of 6 unit square colloums. This can be even more simplified by the equation length times with
base, b = 45m
angle of elevation, aoe = 82deg
height at 86th floor, h1
height above 86th floor, h2 = 123m
total height, h = h1 + h2
using
tan (aoe) = h1/b
=》 h1 = tan (aoe) × b = tan 82 x 45 = 320.2
h = h1 +h2 = 320.2 + 123 = 443.2m
Answer:53km/h
Step-by-step explanation:
you divide 424 by 8 in order to find the unit rate or the amount of kilometers per hour
Answers:
x = 100
y = 25
==============================================================
Explanation:
Angle y and the 25 degree angle are corresponding angle. Because the lines are parallel, this means that y = 25
Check out the attached image. Using a red pen, I extended one of the lines to form a triangle. From the alternate interior angle theorem, we know that one of the angles of the triangle is 75 degrees (alternate interior angles are congruent). Again this stems from the fact that the lines are parallel.
I've also introduced the variable z to help find x. The angles x and z add up to 180 degrees since they form a straight line. So we need to find z before we can find x.
The triangle's angles 25, 75, z add up to 180. Let's solve for z
25+75+z = 180
100+z = 180
z = 180-100
z = 80
Use this to find x
x+z = 180
x+80 = 180
x = 180-80
x = 100
