Mathematics
1 answer:
kozerog [31]4 years ago
8 0

Answer:

60°

Step-by-step explanation:

The radius of the circle is given as 7 ( centre of circle to point C )

The other radius is also 7 ( from centre to point D)

CD = 7

The triangle is therefore equilateral ( all 3 sides = 7 )

The angles of an equilateral triangle are equal and measure 60°

Hence mCD = 60°

Express 15.16 as a mixed number
kap26 [50]
If this is not a typo, and you mean 15.16 as in 15 and 16 hundredths, we can express this into a mixed number.
Mixed numbers are a whole number with the remainder of that number as a fraction.
For example, 1.25 as a decimal = 1 1/4 as a mixed number.
Since we already have our whole number, 15, we need to know what 16 hundredths is simplified as a fraction.
Currently, our mixed number is 15 16/100.
To simplify this, we need to find a common factor that 16 and 100 share.
Since they are both even numbers, let's divide by 2.
16/2 = 8
100/2 = 50.
Our new mixed number is 15 8/50.
Currently our fraction is still even, so divide by 2 again.
8/2 = 4
50/2 = 25
Your new mixed number is 15 4/25.
4 and 25 have no common factors, so the fraction is simplified.
Your answer is:
15.16 is 15 4/25 as a mixed number.
I hope this helps!
