Answer 1

Answer:

MARK ME BRAINLIEST ANSWER PLEASE

Step-by-step explanation:

AC length=2√10. tanb=2. tanc=3. ATQ,. tanc=>p/b=AB/BC=3. AB/BC=3. AB=3BC . By pythogorous theorm:-. AB²+BC²=AC² ...

• ⚘answer is P=10,Q=7

STEP BY STEP EXPLANATIONS

Let think the two numbers are X and y

The difference between them is 3

So,we can write, x-y=3

The difference between their Squares is 51

So,we can write, X^2 - y^2 =51

Let, X^2 -y^2=51

or, (X+y)(x-y)=51

or,(X+y) 3 =51

(x+y)=17

(x−y)=3

2x=20

x=10

(X+y)=17

y=17-10=7

therefore,X=10,y=7(Answer)
