Supplementary angles are angles whose wine up to 180 degrees . Two supplementary angles are such that one angle is 5 degrees les

d1i1m1o1n [39]

The angles are 37° and 143°

Step-by-step explanation:

Supplementary angles are thoe angles that sum up to 180 degrees

In the given case,,

Let x be one angle

Then the other angle will be:

4x-5

So,

$x+ (4x-5) = 180\\x+4x-5 = 180\\5x - 5 = 180\\5x = 180+5\\5x = 185$

Dividing both sides by 5

$\frac{5x}{5} = \frac{185}{5}\\x = 37$

The other angle will be:

$4x-5 = 4(37) - 5 = 148 - 5 = 143$

So,

The angles are 37° and 143°

Set the quadratic = to 0 and solve for time, t:

-16t^2 - 8t + 20 = 0

Reduce this to:

-4t^2 - 2t + 5 = 0

Here a= -4, b= -2 and c =5. Then,

2 plus or minus sqrt( 4-4(-4)(5) )
t = ---------------------------------------------
-8
2 plus or minus sqrt(84)
= ------------------------------------
-8

Finish evaluating this. If either outcome is negative, discard it.
The result will be the number of seconds required for the ball to hit the grnd.
