You should try to divide 192 by the 4 sides on the rectangle.
60 minutes. Take how far it is above ground (20 m) and add it to the absolute value of how far it is below ground (340 m) to get 360 meters, which you divide by the rate of descent (6 m/min) to get 60 minutes.

Answer:
.
Step-by-step explanation:
Find two points on the original line, :
Setting gives , which corresponds to the point .
Setting gives , which corresponds to the point .
Reflect the two points with respect to the -axis by inverting the -coordinate of each point. The point stays the same, whereas the point would be mapped to .
Find the equation of the new line. The slope of the new line would be:
.
Equation of the new line in point-slope form:
.
.
Answer:
C
Step-by-step explanation:
since the triangles are similar then the ratios of corresponding sides are in proportion , that is
= ( substitute values )
= ( cross- multiply )
12 RS = 84 ( divide both sides by 12 )
RS = 7 cm
