1.explain the process of indirect measurement. Create an example situation when indirect measurement would be useful. 2. Solve of x, y, and z in the figure above^^. Show your work

Step-by-step explanation:

(1). Indirect measurement is a method of using proportions to find an unknown length or distance in similar figures.

"The "h" feet tall building with its shadow of 90 feet and 6 feet tall person with its shadow of 15 feet form similar right triangles. Find the height of the building."

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
