Half yearly question (1 Viewer)

[Micro Reflex]

So I had my maths test today. One of the questions had a scalene triangle ABC with side a=90cm and side b=120cm. Everything else was unknown. a) Find the size of angle A. b) Find the area of the triangle.

I only just did it a few hours ago. Sorry this is the best I can provide.

There was a triangle and questions a) and b).

 

[Micro Reflex]

maybe triangle was right-angled?

No it was definitely scalene, no values for any angles. It was just very confusing, i'll just have to take it up with my teacher after the test period

Was the question in scale? If not, then literally from the information you provided it's not doable.

Sorry I can't be of help, there just wasnt enough information for it to make any sense. Are you 100% sure it was scalene? Can you remember if the question had any other important info?

 

[Micro Reflex]

No besides the fact that a) was worth two marks and b) was one. It made no sense but if I can get a copy of the test paper I will post it

They would've given an angle

So I contacted my teacher and he confirmed that it was an honest mistake.
