The ratio of the measurement of an angle to its complement is 1:2. Find the measurement of the angle and its complement.
vodka [1.7K]
We know that these two angles are in the ratio 1:2 and add to 90 because they are complementary

So we can write the equation

x+2x=90
3x=90
x=30

So the first angle measure is 30

Since they are in the ratio 1:2, the second angle is twice 30 so 60

Hope this helps

ehidna [41]

Answer:

110.4622 = 110 (as followers cannot be in decimals).

Step-by-step explanation:

Given, growth rate is 1% = 0.01.

and it is for every 12 hours.

now, f(x) = f(1 + r)^t. where f= 100 (initial followers)

                            r = 0.01.

                             t =10 (1 for every 12 hours. so, 5 days = 120 hours = 10 times)

⇒ f(x) = 100(1+0.01)¹⁰ = 110.4622 = 110 followers.
