3x^(2)+4x-3x-5-2=0
3x^(2)+x-7=0
Discriminat= b^(2)-4ac= 1^(2)-4(3)(-7)= 1-12(-7)=1+84=85
The discrimination is bigger than 0 (delta>0) therefore there are 2 real solutions

Answer:

tangent = opposite leg / adjacent leg
tan ∠F = DE/ EF
tan ∠F = 24/7

<u>Option D</u>

Sine and cosine are same for complementary angles.

Complementary of 67° is 90° - 67° = 23°.
sine 67° = cosine 23°

The measure of the supplement of an angle is 84° less than the measure of the angle. Find the measures of the angles

babunello [35]

Let the measure of angle be 'x'

Since, the measure of the supplement of an angle is 84° less than the measure of the angle.

Therefore, measure of supplement of x = x - 84°

The measure of two supplementary angles is 180 degrees.

$x + x -84^\circ = 180^\circ$

$2x -84^\circ = 180^\circ$

$2x =84^\circ + 180^\circ$

$2x =264^\circ$

$x =132^\circ$

So, the measure of angle = $x =132^\circ$

Its supplement = x - 84° = 132° - 84°

= 48°

So, the measure of supplement of angle is 48 degrees.
