The measures of two supplementary angles are 12q - 9 and 8q + 14. Find the measures of the angles.

1 answer:

8 0

12q - 9 + 8q + 14 = 180
20q + 5 = 180
20q = 175
q = 8.75
angle 1 : 12(8.75) - 9 = 96
angle 2 : 8(8.75) + 14 = 84
Check: 84 + 96 = 180

Find the value of k by quardractic equation two real and equal roots 5x - 2kx +20=0

kotegsom [21]

Answer:

k = +10 or -10

Step-by-step explanation:

It's given in the question that the roots of the eqn. are real and equal. So , the discriminant of the eqn. should be equal to 0.

$= > {b}^{2} - 4ac = 0$

$= > {( - 2k)}^{2} - 4 \times 5 \times 20 = 0$

$= > 4 {k}^{2} - 400 = 0$

$= > 4( {k}^{2} - 100) = 0$

$= > {k}^{2} - 100 = 0$

$= > k = \sqrt{100} = + 10 \: or \: - 10$
