Answer: the equation to determine the value of n is 5n = 105
Step-by-step explanation:
The measure of angle a is n degrees. The measure of angle b is four times angle a. This means that the measure of angle b would be
b = 4n
The measure of angle c is 75 degrees. Since the sum of the interior angles of a quadrilateral is 180 degrees, then the equation to determine the value of n would be
a + b + c = 180
Therefore,
n + 4n + 75 = 180
5n = 180 - 75
5n = 105
n = 105/5
n = 21

Step-by-step explanation: .7 IN 5 SECONDS
Answer:
Yes they are proportional!
The factors of 28 that we can use in these fractions are 4 and 7. To find if these are proportional, just simplify 8/28. To do so divide the numerator (top) and the denominator (bottom) both by 4...
8/28 / 4 = 4/7
Now that you have both with the same denominator, you can evaluate if 3/7 and 4/7 are proportional. In this case they are.
Hope this helps! :)
