Answer:
<u>Step-by-step explanation:</u>
EQ1: x + y = 12 --> x = 12 - y
EQ2: xy = 15
Substitute x = 12-y into EQ2 to solve for y:
(12 - y)y = 15
12y - y² = 15
0 = y² - 12y + 15
↓ ↓ ↓
a=1 b= -12 c=15
Now, let's solve for x:
Lastly, find x² + y² :

Answer:
AB = 8.857 cm
Step-by-step explanation:
Here, we are given a <em>right angle</em> in which we have the following things:
Side <em>BC </em>is the hypotenuse here.
We have to find the side <em>AB</em>.
Trigonometric functions can be helpful to find the value of Side AB here.
Calculating :
Sum of all the angles in is
.
We know that <em>cosine </em>of an angle is:
So, side AB = 8.857 cm .
