Question

Calculate the length of the side missing in this figure of right angled triangle

plz help me ​

Answer 1

Answer:

By Pythagoras theorem

(Hy)^2=(base)^2+(perpendicular)^2

(2.5)^2=(1.5)^2+(p)^2

6.25-2.25=(p)^2

4=p^2

p=√4=2

Answer 2

Answer:

${p}^{2} + {b}^{2} = {h}^{2} \\ {p}^{2} + {1.5}^{2} = {2.5}^{2} \\ {p}^{2} = {2.5}^{2} - {1.5}^{2} \\ {p}^{2} = 6.25 - 2.25 \\ {p}^{2} = 4 \\ p = \sqrt{4} \\ p = 2$
