First put it in standard form:
<span>x^2 −14x -15 =0
a =1 b =-14 c=-15
Then use the quadratic formula:
x = [-b +-sq root (b^2 - 4ac)] / 2a
x = [--14 +- sq root (14^2 -4*1*-15] / 2*1
x = [14 +-sq root (196 +60)] / 2
</span><span>x = [14 +- 16] / 2
x1 = 15
x2 = -1
</span>
Answer:
The measure of the angle is 34 deg.
Step-by-step explanation:
Let the angle measure = x
"the supplement of an angle is twenty-four degrees less than five times the angle"
The supplement's measure is 5x - 24
The measures of supplementary angles is 180 deg.
x + 5x - 24 = 180
6x - 24 = 180
6x = 204
x = 34
Answer: The measure of the angle is 34 deg.
Answer:
M=55
Step-by-step explanation:
Since the lines are parralel then the angles would have to equal 180 degrees. You would sybtract 180-125 and get 55
The answer to the first one would be 30.
