I think the answer is Sample 4.
Hope this helps!
Answer:
-5 and 8
in question 3and 4 we have to evaluate
The ratios are both identical
sin x = perpendicular/hypotenuse = 3/5
cosy = base/hypotenuse = 3/5
Answer:
the answer is a) 100*
the angles it is bigger than is an acute angle (below 90)* and a right angle (exactly 90*) so the answer is anything above 90* and so it has to be 100*
Answer:
Step-by-step explanation:
To solve this you need the Law of sines
- sin A / a = sin B / b = sin C / c
a, b, c are the sides opposite to angles A, B and C respectively
Applied to the given triangle we have one side given, the opposite angle to be found.
- sin 28 / x = sin (180 - 28 - 126) / 8.2
- sin 28 / x = sin 26 / 8.2
- x = 8.2 sin 28 / sin 26
- x = 8.8 (rounded)
