Astory of ratios
lesson 10 703
problem set

for each question, use angle relationships to write an equation in order to solve for each variable. determine the
indicated angles. you can check your answers by measuring each angle with a protractor.
1. in a complete sentence, describe the relevant angle relationships in the following diagram. find the measurement
of zdae.
to
65°
f

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

it would take 7/10 of an hour too fill the pool.
