The picture below shows a right-triangle-shaped charging stand for a gaming system: Which expression shows the length, BC, of the base of the stand?
7 over tan 55°
7(cos 559)
7 over sin 55°
7(tan 559)

For the given triangle, the tan of angle A equals
Step-by-step explanation:
Step 1:
In the triangle, the given angle is 70°, the opposite side, AC's length is 9 inches. Assume the adjacent side BC's length is x inches. To determine the adjacent side's length, we determine the tan of the angle. To calculate the tan of an angle, we divide the opposite side's length by the adjacent side's length.

Step 2:
The length of the opposite side = 9 inches.
The length of the adjacent side = x cm.

So BC of the given triangle measures 3.2758 inches.

The answer is e &
