Answer:

Please find the solution in the image attached below.

Step-by-step explanation:

Tcos60 -2T sin(90-theta) = 0

Tcos60 = 2T(cos theta)

cos 60 = 2cos theta

cos60 = 2cos theta

1/4 = cos theta

theta = 75.5

So the angle to the vertical = 90-75.5 = 14.5

Resolving perpendicular

Tsin60 + 2Tsin75.5 - 2g = 0

T(sin 60 + 2sin75.5) = 2g

T = 19.6/sin 60 + 2sin75.5

T = 19.6/1.936 + 0.866

T = 19.6/2.802 = 7.0N

Hope this helps!

Select the correct answer. The product of two numbers is 21. If the first number is -3, which equation represents this situation

Komok [63]

Answer:

Step-by-step explanation:

Since it's the product, the two numbers must be multiplied together. -3 * x will equal 21, so -3x=21. By dividing both sides by -3, we see that x=-7
