Answer:
0.51, √5, 5.1% x 10^-3
Step-by-step explanation:
Answer:
a. 12/13
Step-by-step explanation:
Sin is opposite over hypotenuse.
Opposite side of K is 12 and your hypotenuse is 13
Four times the sum of a number and 15 is at least 120
Let ‘x’ represent the number.
"The sum of a number and 15"
This can be written mathematically as x + 15
Given that 4 times this sum is at least 120,
This means that 4 times the sum is greater than or equal to 120
This can be written mathematically as 4(x + 15) >= 120
Solving for x
4(x + 15) >= 120
4x + 60 >= 120
4x >= 120 – 60
4x >= 60
x >= 60/4
x >= 15
x is greater than or equal to 15

Option B
The sum of the measures of the exterior angles of a 53 - gon is 360 degrees
<em><u>Solution:</u></em>
The formula for sum of exterior angles "n" is:

Distribute 180

Therefore, sum of measure of exterior angles is 360 degrees
<h3>Sum of the measures of all the exterior angles of any polygon, irrespective of its number of sides is always 360 degrees</h3>
Thus, in a 53 gon, sum of measure of exterior angles is 360 degrees
