Two angles are supplementary if their sum is 180 degrees.
Here we are given:
Angle GHI measures (28x + 40)° and angle JHI measures (7x)°.
Sum of angle GHI and JHI is 180.



dividing both sides by 35,
x=4
Now let us find angle JHI
angle JHI = 7x = 7*4 =28
Answer : Angle JHI is 28 degrees.
The given numbers are a set of points. To convert this into a linear data set, you can do data fitting. The easiest way to do this is using a software. In this case, I used MS Excel. You plot the points and set a linear trendline. The linear equation for this set of data is: y = 0.286x + 0.784
You can refer to the image to further understand the procedure.
Answer:
The amount of interest Coach Cliffman earned after 3 years is $108.
Step-by-step explanation:
The equation for simple interest is A = P(1 + rt). To determine the revenue earned, subtract the principal amount ($1800) from the total accured amount (principal + interest). The equation for simple interest is A = P(1 + rt), <em>P </em>meaning principal interest, <em>r</em> being the rate of interest per year in decimal form, and <em>t</em> as time in years.
Let P = $1800, r = .02, and t = 3 and you'll end up with a total accrued amount of $1908. Finally, subtract 1908-1800 to get your answer of $108.
It would be B. 68
