For the points a and b, you are given the x value of a point on the graph. This means all you have to do is plug in -3 into the equation, and 5 into the equation
This gives -4.3(-3) and -4.3(5)
The points end up being (-3,12.9) and (5,-21.5), final answer
Answer:
The angles would be 6 degrees and 84 degrees
Step-by-step explanation:
In order to find this we must first note that complementary angles have a sum of 180. Now we can set the smaller angle as x and the larger angle as 14x. Now find the sum and set equal to 180.
x + 14x = 90
15x = 90
x = 6
This makes the first angle 6 and we can find the larger angle.
14x
14(6)
84
Consecutive angles in a parallelogram are supplementary angles which when added together equal 180 degrees.
The ratio is 7:5 so we would have:
7x + 5x = 180
Simplify:
12x = 180
Divide both sides by 12:
X = 15
So one angle is 7 x 15 = 105 degrees
The other angle is 5 x 15 = 75 degrees
An obtuse angle is an angle greater than 90 degrees.
The obtuse angle would be 105 degrees.
