Question

in an adjoining figure find x +y


don't give chorus ans​

Answer 1

Answer:

x+y=21m

Step-by-step explanation:

In ΔABP,

(AP)²=(AB)²+(BP)²

(15)²=(9)²+(x)²

225=81+x²

x²=225-81

x²=144

x=√144

x=12m

In ΔCDP,

(CP)²=(CD)²+(DP)²

(15)²=(12)²+(y)²

225=144+y²

y²=225-144

y²=81

y=√81

y=9m

x+y=12+9=21m

Answer 2

Answer ⬇️

1) In ∆ ABP, Angle ABP = 90°

(AP)² = (AB)² + (BP)² ( By Pythagoras theorem)

(15)² = (9)² + x²

225 = 81 + x²

x² = 225 - 81

x² = 144

x = 12 m ...( Taking square root)

2) In ∆CPD , Angle CDP = 90°

(CP)² = (CD)² + (DP)²

(15)² = (12)² + y²

225 = 144 + y²

y² = 225 - 144

y² = 81

y = 9 m ( Taking square root)

So, x + y = 12 + 9 = 21m
