Hello! Your answer is 7 degrees.
A set of complementary angles are ones which, when their measurements are added, will equal up to 90 degrees. For example, the complementary angle of a 80 degree angle would be 10 degrees. A supplementary angle also falls in the same category, however it is adding up to 180 degrees. The way I remember which one is which is that <u>c comes first in the alphabet, and 90 degrees comes before 180 degrees.</u>
Applying that knowledge, 83 plus the complementary angle must equal 90. 83 + 7 = 90, therefore, the complementary angle measures 7 degrees.
Hope this helps!
Answer:
You would do 18/2 first.
Step-by-step explanation:
In order of P.E.M.D.A.S (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction), Division is the first main operation you would do, therefore making 18/2 the first thing to do.
To find the distance in one turn of the wheel you have to find the circumference of the wheel.
Circumference = pi x d
= 3.14 x 5
= 15.7 cm
therefore the rollerblade wheel will travel 15.7 cm per rotation
hope this helps! if you did not understand a step or concept please let me know!
The answer would be 3.175 kg
