Since the ratio of the sides of ABC to PQR is 4:6, the ratio of the areas of ABC to PQR is 16:36.

So 40cm2 * 36/16 = 90cm2.

Answer:

The area of ΔPQR = 90 cm²

Step-by-step explanation:

Points to remember

If two triangles are similar, then ratio of their areas is equal to square of ratio of their corresponding sides.

It is given that,

ΔABC ~ ΔPQR

<B = < Q

<C = <R

ar(ΔPQRC) = 40 cm²

<u>To find the area of ΔPQR</u>

We have ,

ar(ΔABC)/ar(ΔPQR) = AB/PQ

40/ar(ΔPQR)= (4/6)² = 16/36

ar(ΔPQR) =  (36 * 40)/16 = 90 cm²

Therefore area of ΔPQR = 90 cm²

Find the tangent of both angle A and angle B. Ignore what the picture says the numbers are the same.
Elena-2011 [213]
For the angle A we have:
 tan (A) = C.O / C.A
 tan (A) = 10/24
 Simplifying we have:
 tan (A) = 5/12
 For angle B we have:
 tan (B) = C.O / C.A
 tan (B) = 24/10
 Simplifying we have:
 tan (B) = 12/5
 Answer:
 
The tangent of angles A and B is given by:
 
tan (A) = 5/12
 
tan (B) = 12/5

A recent survey suggests that 85% of college students have a job, 54% live on campus, and 42% have a job and live on campus. Wha

\frac{97}{100} probability that a randomly chosen college student either has a job or lives on campus.

What is probability?

  • Probability is an area of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely a statement is to be true.
  • The probability of an event is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.

To find the probability that a randomly chosen college student either has a job or lives on campus:

Given: 85% of college students have a job, 54% live on campus, and 42% have a job and live on campus.

So, out of 100 students, 42 students either has a job or live on campus.

43 college students have a job and 12  live on campus.

So, 43 + 42 + 12 = 85 + 54 - 42

85 + 12 = 139 - 42

97 = 97

Therefore, \frac{97}{100} probability that a randomly chosen college student either has a job or lives on campus.
