Answer:
20 degrees
65 degrees
95 degrees
Step-by-step explanation:
Add the numbers in the ratio.
4+13+19=36
Divide the sum of all the angles in a triangle by the sum of the numbers in the ratio.
180/36=5
Multiplying 5 to each of the numbers in the ratio will give the measures of the angles.
4(5)=20 degrees
13(5)=65 degrees
19(5)=95 degrees
The lcm is 72 hence the fractions are 15/72 & 28/72
Answer:
<h2>-1 3/7 is larger</h2>
Step-by-step explanation:
To figure out which is larger, convert each of these mixed numbers to decimals.
-1 3/7 = -1.42857142857
-1 1/2 = -1.5
Negative numbers are larger the closer they are to 0. So, -1 is larger than -2, since -1 is closer to 0.
Since -1.5 < -1.43, -1 3/7 is larger than -1 1/2 since it is closer to 0.

= 9n + 63
generate the first few terms using the recursive equation
f(1) = 72
f(2) = 72 + 9 = 81
f(3) = 81 + 9 = 90
f(4) = 90 + 9 = 99
the sequence is 72, 81, 90, 99, .....
This is an arithmetic sequence whose n th term formula is
= + (n - 1 )d
where is the first term and d the common difference
d = 99 - 90 = 90 - 81 = 81 - 72 = 9 and = 72
= 72 + 9(n - 1) = 72 + 9n - 9 = 9n + 63 ← explicit formula
