fomenos

Answer:

Step-by-step explanation:

Triangle:

Base = 4 units

Height = 3 units   {perpendicular height}

Area=\frac{1}{2}*base*height\\\\=\frac{1}{2}*4*3\\\\=2*3

= 6 square units

Rectangle:

To find the area count the number of squares. Number of square = 6

Area = 6 square  units

or You can find the area of the rectangle as bellow also

Length = 3 units

Width = 2 units

Area = length*width

       = 3*2

       = 6 square units

Both the triangle and rectangles has the same area 6 square units

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
