Question

can someone help me with this

Answer 1

by using the pytogoras theorem,
h²=p²+b²
10²=p²+6²
100=p²+36
p²=100-36
p²=64
p=√64
p=8
so,
a=8

that's all,

Answer 2

As we know,
${h }^{2} = {p }^{2} + {b}^{2}$
${10}^{2} = {a}^{2} + {6}^{2}$
$100 = {a}^{2} + 36$
$100 - 36 = {a}^{2}$
$64 = {a}^{2}$
$a = \sqrt{64}$
$a = 8$
