<h3>How to find the side of a right triangle?</h3>A right triangle has one of its angles as 90 degrees. The side of a right angle triangle can be found using trigonometric ratios.
The sides CD and BD can be found using similar triangle principle.
In similar triangles, corresponding sides are always in the same ratio.
Therefore, the following proportion can be established as follows;
Hence,
cross multiply
4 × 4 = 12.8 CD
16 = 12.8CD
divide both sides by 12.8
CD = 16 / 12.8
CD = 1.25 ft
BD = 1.25 + 12.8 = 14.05 ft
Therefore, the front of the base is 1.25 ft and the total base is 14.05 ft.

Answer:
John work as a security guard job <u>27 hours</u> and as a landscaper <u>33 hours</u>.
Step-by-step explanation:
Given:
John works two jobs.
As a security guard he earns $8.50 per hour and as a landscaper he earns $14 per hour.
One week John worked a total of 60 hours and earned $691.50.
Now, to find hours he work at each job.
Let the job of security guard be hours.
And the job of landscaper be hours.
So, the total hours John worked in a week:
⇒ ............( 1 )
<em>Now, the money earned by John in a week:</em>
<em>Putting the equation ( 1 ) in the place of :</em>
⇒
⇒
<em>Moving variables on one side and the other we get:</em>
⇒
⇒
<em>Dividing both sides by 5.50 we get:</em>
⇒
<u>As a security guard job he worked 27 hours</u><u>.</u>
Putting the value of in equation ( 1 ) we get:
⇒
<u>As a landscaper he worked 33 hours</u>.
Therefore, John work as a security guard job 27 hours and as a landscaper 33 hours.
