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

What is the solution?
galina1969 [7]

Answer:

y=60 x=16

Step-by-step explanation:

the triangles are identical so 92+y=3y-28 so solve that for y:

                                                     -y      +28

                                                  120=2y                                                                            .                                                  /2      /2

                                                  60 = y so y=60

and 6x+2=3x+50 and solve that for x: which gets x = 16

Then are you supposed to plug it in to the numerical equvilant to the angles and sides becuase if so:  B and E is 152, AC and DF are 98

Hope this helps and brainliest would be greatly appreciated! Thanks!
