Answer:

Part A: equations B and D are true

Part B: expression B is equal to tan(g)

Step-by-step explanation:

In the given triangle, sin(g) = cos(h) and cos(g) = sin(h).

___

Part A

Based on the above, selection B is true.

Based on the above, the equation of D becomes: sin(h)+sin(g) = sin(g) +sin(h), which is true.

Selections B and D are true

___

Part B

Based on the above tan(g) can also be written ...

tan(g) = cos(h)/sin(h) . . . . . corresponds to selection B
