natta225 [31]

Answer:

53 marks

Step-by-step explanation:

To sue a linear equation to solve the given problem, we must assign a function to the score of one of them. Let the score of Azmah be N. Then given that Azmah scored 17 marks more than Yazid, Yazid's score will be

= N - 17

Given that Suzana's score is twice of Yazid's score, then Suzana's score

= 2(N - 17)

If their total score is 161 then

N + N - 17 + 2(N - 17) = 161

4N = 161 + 51

4N = 212

N = 53 . This is Azmah's score

Determine the length of the unknown sides for the right triangle
alisha [4.7K]

Answer:

Below in bold.

Step-by-step explanation:

sin 66.4 = opposite side / hypotenuse

sin 66.4 = 21.3 / y

y = 21.3 / sin 66.4

y = 23.24.

tan 66.4 = 21.3 / x

x = 21.3 / tan 66.4

x = 9.31.
