Hey Emaanu ☺️

Given :

RQ = QS

RS = 14.8 cm

PS = 7.5 cm

To Find :

a = ?

Solution :

In triangle SQR

Let QS = QR = g

Now,

P = QS = g

B = QR = g

H = RS = 14.8(given)

By Pythagoras Thm.

${p}^{2} + {b}^{2} = {h}^{2}$

${g}^{2} + {g}^{2} = {14.8}^{2} \\ 2 {g}^{2} = 219.04 \\ {g}^{2} = \frac{219.04}{2} \\ {g}^{2} = 109.52 \\ g \: = \sqrt{109.52} \\ g \: = \: 10.465 \: cm \\ g = 10.47 \: cm$

PQ = PS + QS

QS = QR = g = 10.47 cm

PQ = 7.5 +10.47

PQ = 17.97 cm

Now, in triangle PQR

P = PQ = 17.97 cm

B = QR = 10.47 cm

H = a

${p}^{2} + {b}^{2} = {h}^{2} \\ {(17.97)}^{2} + {(10.47)}^{2} = {a}^{2} \\ 322.92 \: + \: 109.62 \: = {a}^{2} \\ {a}^{2} = 432.54 \\ a \: = \sqrt{432.54} \\ a \: = 20.79 \: cm \: \\ a \: = 20.8 \: cm$

I Hope it helps you ☺️ ✌️ ✌️
