Answer:y = 15
Step-by-step explanation:
<u>Concept:</u>
Here, we need to know the idea of similar triangles.
Two triangles are similar if they have the same ratio of corresponding sides and equal pairs of corresponding angles.
If you are still confused, please refer to the attachment below for a graphical explanation.
<u>Solve:</u>
<em>Set up the proportion between the sides</em>
Small / Big = Small / big
10 / 22 = y / 33
<em>Cross-multiply to simplify the proportion</em>
22 · y = 33 × 10
22y = 330
<em>Divide 22 on both sides</em>
22y / 22 = 330 / 22
y = 15

Answer:
Step-by-step explanation:
Here we are given that a polynomial has zeros as 2 , i and -i . We need to find out the cubic polynomial . In general we know that if are the zeros of the cubic polynomial , then ,
Here in place of the Greek letters , substitute 2,i and -i , we get ,
Now multiply (x-i) and (x+i ) using the identity (a+b)(a-b)=a² - b² , we have ,
Simplify using i = √-1 ,
Multiply by distribution ,
Simplify by opening the brackets ,
Rearrange ,
