Question

please tell the answer the question is given in the photo attached. please give step by step explanation​

Answer 1

Answer:

find the angle adjacent to 20 and 16 using the formula cos teta = adj/hyp

.

and then find y using the formula sin teta = opp / adj

Answer 2

Step-by-step explanation:

i ) H² = B² + P²

P² = 20 ²- 16²

P² = 4cm²

P= √ 4

P= 2

ii ) H² = 9² + 12²

H² = 81 + 144

H² = 225 cm²

H = √ 225

H = 15

iii ) B² = (- 24²) + 25 ²

B² =(- 576 )+ 625

B² = 49 cm²

B= √ 49

B= 7

i hope it helps sorry for the changes i did not notice that we have to take different things ( P , H , B )in different question .

i am really sorry for the silly mistake
