Answer:

∠ A ≈ 59.5°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinA = $\frac{opposite}{hypotenuse}$ = $\frac{BC}{AB}$ = $\frac{56}{65}$ , then

A = $sin^{-1}$ ( $\frac{56}{65}$ ) ≈ 59.5° ( to 1 dec. place )

100 cm = 1m

To find 60 000cm, multiply by 600 :
60 000 cm = 600m

To convert from m to km, divide by 1000 :
600m ÷ 1000 = 0.6km

If A : B = 4 : 5 and B : C = 3 : 2, find A : B : C.

Sindrei [870]

Answer:

12 : 15 : 10

Step-by-step explanation:

Let A = 4x, the B = 5x

Let B = 3y, then C = 2y

B = 5x = 3y, so y = (5/3)x

Let x = 3t, so y = 5t

Then A = 4x = 4(3t) = 12t

B = 5x = 5(3t) = 15t

C = 2y = 2(5t) = 10t

so A : B : C = 12t : 15t : 10t = 12 : 15 : 10

Step-by-step explanation:

6/7 6 divided by 7 = 0.86

proper- doesn't go over 1

3/10 3 divided by 10 = 0.30

proper - doesn't go over 1

4/5 4 divided by 5 = 0.8

proper- doesn't go over 1

10/3 10 divided by 3 = 3.33

improper- goes over 1

PROPER- When divided, <u>DOESN'T</u> go over 1 whole

IMPROPER- When divided, <u>DOES </u>go over 1 whole
