Question

solve for x
Pls help me ​

Answer 1

Answer:

root400=20

Step-by-step explanation:

by Pythagoras theorem

12²+16²=x²

144+256=x²

400=x²

x=20

Answer 2

ANSWER:

• Value of x is 20 units.

GIVEN:

• A Right angled triangle with sides 16 units and 12 units.(Excluding Hypotenuse).

TO FIND:

• Value of 'x'.

SOLUTION:

Pythagoras theorem:

• The square of the hypotenuse is equal to the sum of the square of other two sides.
• (Perpendicular)² +(Base)² = (Hypotenuse)² ...(i)

Putting the values in the formulae:

=> (16)²+(12)² = x²

=> 256+144 = x²

=> 400 = x²

=> x = √400

=> x = 20 unit.

Value of'x' is 20 units.

NOTE:

• This type of questions can be solved by using Pythagoras theorem.
• (Perpendicular)² +(Base)² = (Hypotenuse)².
