Answer:
x = 8
Step-by-step explanation:
The triangle is isosceles with legs congruent, both x
Using Pythagoras identity in the right triangle
x² + x² = 16²
2x² = 256 ( divide both sides by 2 )
x² = 128 ( take the square root of both sides )
x = =

Answer:
he Present age of Prisca will be 4 years .
Step-by-step explanation:
Given as :
The ratio of present age of Prisca and Ashmaal = 2 : 3
Let The present age of Prisca = 2 x years
Let The present age of Ashmaal = 3 x years
After 4 years , the ratio of present age = 4 : 5
i.e =
Or, 5 × (2 x + 4) = 4 × (3 x + 4)
Or, 10 x + 20 = 12 x + 16
Or, 12 x - 10 x = 20 - 16
Or, 2 x = 4
∴ x =
i.e x = 2
So, The present age of Prisca = 2 x = 2 × 2 = 4 years
And The present age of Ashmaal = 3 x = 3 × 2 = 6 years
Hence, The Present age of Prisca will be 4 years . Answer
