Answer:

B. StartFraction R Y Over R S EndFraction = StartFraction R X Over R T EndFraction = StartFraction X Y Over T S EndFraction

i.e $\frac{RY}{RS}$ = $\frac{RX}{RT}$ = $\frac{XY}{TS}$

Step-by-step explanation:

Two or more shape or figures are similar when their sides and angles can be compared appropriately.

In the given figure, ΔRXY is within ΔRST. Since the two triangles are similar, then their length of sides can be compared in the form of required ratios.

So that by comparison,

$\frac{RY}{RS}$ = $\frac{RX}{RT}$ = $\frac{XY}{TS}$

Therefore, the correct option to the question is B.

1. a) if 60%% students passed in Physics, 55% pass in Math and 40% fail in both subjects, what percent of students are pass in b

hammer [34]

Answer:

75%

Step-by-step explanation:

Percent. of students passed who in physics =60% Percent. of students who passed in maths = 55%

Total percent. who passed = (60+55)%

= 115%

Percent. of students who failed= 40%

Percent. of students who passed = (115 - 40)%

= 75%.

What is the area of the square below?

Sedbober [7]

Answer:

O C. 5.76 in2

Step-by-step explanation:

To find the area of a square, the formula is

length x width = area

length = 2.4

width = 2.4

2.4in x 2.4in = 5.76 in2

in2 is the part of the answer since in x in = in2

Can someone help me out?

stira [4]

Answer:

40 degrees

Step-by-step explanation:

A triangle solver tool can find the angle easily. It is 39.8°, which rounds to 40°. Apps are available on some calculators, on the Internet, and for iOS and Android phones and tablets.

___

You may be expected to solve this using the Law of Cosines. If we name the sides ...

a = 1.75
b = 3.00
c = 2.00

the law of cosines tells us the relationship is ...

c² = a² + b² -2ab·cos(θ)

Then the angle is ...

θ = arccos((a² +b² -c²)/(2ab)) = arccos((3.0625 +9 -4)/(2·1.75·3))

= arccos(8.0625/10.5) ≈ 39.838° ≈ 40°
