Please, please, please help me!!!

For this question, you need to decide whether to use sin cos or tan.
You have the hypotenuse and Ф but you need to find the opposite side.

For those reasons you would use sin, as it has all three in its triangle,
The equation for opposite = sinФ * hypotenuse
So sin49 * 12.38 = 9.3cm.

The answer is 9.3cm.

Hope this helps.

Which expression is equal to p + (q + r)
lana66690 [7]

Answer:

the answer for me would be (p+q)+r

here is why I think so

q +pr ( the pr close-by together in maths means multiple so that's out) same goes for C and A it has a negative so that's not equal.
