The measure of two complementary angles are in the ratio 1 : 4. What are the degree measures of the two angles?
AlladinOne [14]
Since the angles are complementary, they add to 90°. So we can write the equation:
x represents the first angle, and 4x represents the second
x+4x=90
5x=90
x=18 

So the first angle is 18° and the second is 72° (18*4)

Hope this helps

PLEASE HELP ASAP, THANK YOU
nlexa [21]

First step is to plot all the given coordinates in the xy plane.

Notice that after plotting the points A, B, C and D, we have got the figure ABCD is a trapezium with bases AD = 4 units, BC = 6 units and height: DE= 5 units.

Formula to find the area of trapezium is:

Area = \frac{(AD+BC)}{2} *DE

= \frac{4+6}{2} *5

=\frac{10}{2} *5

= 5 * 5

= 25 square units.

So, third choice is correct.

Hope this helps you!
