Answer:
1. 192 m^2
2. 396 ft^2
3. 108 m^2
Step-by-step explanation:
1. 4*8*6 = 192
2. 9*8*11 = 792
792/2 = 396
3. 4*3*9 = 108
For #16, it can be assume that the two angles are linear, so set them both equal to 90 (9x+x-10=90) and solve for x. Once you have x, plug it into the equations to find the measure of both angles. If both your final answers are added, they should equal 180. If not, go back and try to find where you messed up.
Answer:
Step-by-step explanation:
The given trigonometric identity is .
Jana has to recall that, the cosine function is an even function.
For that matter, .
Jana has to apply this property by substituting for in the given identity to obtain,
.
Note that, the sine and the tangent functions are odd functions
9 miles because 3/4 x 3 is 2.25 then multiply 2.25 and 4
