Answer:
Step-by-step explanation:
<u>Use both points and find the slope:</u>
- m = (1 - 4) / (8 - 4) = - 3/4
<u>Find the line, using point-slope form and point (4, 4):</u>
- y - 4 = - 3/4(x - 4)
- y - 4 = - 3/4x + 3
- y = - 3/4x + 7
Answer:
measure of larger angle = 240 degrees
measure of each of the smaller angles = 120 degrees
Explanation:
In any polygon, the sum of measures of interior angles can be calculated using the following rule:
sum of interior angles = (n-2)*180 where n is the number of sides
Now, for an octagon, n=8, this means that:
sum of measures of interior angles = (8-2)*180 = 1080°
An octagon has 8 interior angles, one of which is twice the measure of the others.
Assume that each of the 7 smaller angles is x degrees and that the larger angle is 2x degrees
Computing their summation, we will find that:
x + x + x + x + x + x + x + 2x = 1080
9x = 1080
x = 120
This means that:
each one of the smaller angles = x = 120 degrees
the larger angle = 2x = 2 * 120 = 240 degrees
Hope this helps :)
Answer: 3rd one
Rearrange the original equation so it fits the model of : ax^2+bx+c=0
Then use the quadratic formula to find all possible answers.
rectangle has a length of
18 feet. The width is x feet
less than the length. If the
area must be less than 216
square feet, what could be
the measurement of the
width?
