Answer 1

Answer:

2)i) 16cm. ii) 5cm

Step-by-step explanation:

2) i) the triangle is a right angle triangle.

let the height be = x

so , by Pythagoras theorem,

height² + base² = hypotenuse ²

=>x²+ 12² = 20²

=>x²+144=400

=>x²=400-144

=>x = √256

=>x = 16cm

ii) this triangle is a right angle triangle.

so, let the hypotenuse be = x

by Pythagoras theorem,-

4²+3²=x²

=>16+9=x²

=>x=√25

=>x=5cm.
