100% will be closer to 95% after rounding-off

100 will be closer because you already passed 85...so if you ever go through a problem like this it will always be th higher number for example, what is 195% closer to 185% or 200%... the answer would be 200%

Jessica is a custodian at Oracle Arena. She waxes 20 square meters of the floor in 3/5 of an hour. She waxes the floor at a cons

Maslowich

Divide 20 by 3 to see how much she would wax in 1/5 of an hour.
20/3= 6.66666667
6.66666667 * 5 =

Use the diagram, which is not drawn to scale to find AD if you know that AC=24 & BC=12

Firdavs [7]

Answer:

Option b. $AD=18\ units$

Step-by-step explanation:

step 1

In the right triangle ABC

<em>Find the sine of angle CAB</em>

$sin($ ---> the sine of angle CAB is equal to divide the opposite side angle CAB (BC) by the hypotenuse (AC)

substitute

$sin($

simplify

$sin($ ---->equation A

step 2

In the right triangle BDC

<em>Find the sine of angle CBD</em>

$sin($ ---> the sine of angle CBD is equal to divide the opposite side angle CBD (DC) by the hypotenuse (BC)

substitute

$sin($ ----> equation B

step 3

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

Triangles ABC and BDC are similar by AA Similarity Theorem

therefore

m∠CBD≅m∠CAB

equate equation A and equation B

$\frac{DC}{12}=\frac{1}{2}$

solve for DC

$DC=\frac{12}{2}=6\ units$

step 4

Find the value of AD

$AD=AC-DC$

substitute the values

$AD=24-6=18\ units$
