Let complementary angle be x,
Then the other angle is 4x
x + 4x = 90 ( complementary angles)
5x = 90
x = 90/5
x = 18,
The measure of the smaller angle = 18
And the measure of the larger angle = 4x
= 4 * 18
= 72
The supplementary of the larger angle is,
Let y be the other supplementary angle.
72 + y = 180 ( Supplementary angles)
y = 180 - 72
y = 108.
Hence, the other supplementary angle is 108 degrees.
Hope you understood. Plzzz let me know if you have any doubts.
Answer:
Step-by-step explanation:
The picture of the question in the attached figure
we know that
In the right triangle of the figure

Answer:
Margin of error =z-score value for chosen confidence level×population standard deviation
Assuming a 95% confidence level , then
z=1.96
standard deviation=5.75
Margin of error= 1.96×5.75=11.27
