Answer:

AC ≈ 17.3 cm

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan68° = $\frac{opposite}{adjacent}$ = $\frac{AC}{AB}$ = $\frac{AC}{7}$ ( multiply both sides by 7 )

7 × tan68° = AC , then

AC ≈ 17.3 cm ( to 1 dec. place )

We will use tangent here as we are finding the opposite with the adjacent given.

So we can simply just put this into a calculator:

tan(68°) × 7 cm = AC

tan(68°) × 7 cm = 17.3 cm

A 20-foot ladder is leaning against a tree. The bottom of the ladder is 12 feet away from the bottom of the tree. Approximately

arsen [322]

Pythagorean theorem is a^2 + b^2 = c^2. the hypotenuse is always the longest, so lets plug in the values.

a^2 + 12^2 = 20^2
if we simplify, we get a^2 + 144 = 400

then subtract 400-144 = 256
then find the sq. root of 256 = 16.

the answer is 16 feet

Joseph earns $15 for every lawn he mows. Is the amount of money he earns proportional to the number of lawns he mows? Make a tab

Vedmedyk [2.9K]

Given that Joseph earns $15 for every lawn he mows.

so if he mows lown 1 time then his earning = $15

if he mows lown 2 time then his earning = $15*2= $30

if he mows lown 3 time then his earning = $15*3= $45

if he mows lown 4 time then his earning = $15*4= $60

if he mows lown 5 time then his earning = $15*5= $75

So the required table will be:

From the table we can see that Joseph's earning increases by $15 each time so we can say that YES, the amount of money he earns proportional to the number of lawns he mows.
