Alja [10]3 years ago
6 0

Answer:

b = 25.03,

c = 32.67   to the nearest hundredth.

Step-by-step explanation:

To find b and c you can use the trigonometry of a right angled triangle.

tan 50 = b / 21

b = 21 tan 50

b =  25.03

cos 50 = 21 / c

c = 21 / cos 50

= 32.67

Vsevolod [243]

The order from least to greatest is 0<u>.8%, 0.556, 1.2 and 10/8</u>

<h3>Ordering of numbers</h3>

In order to order the given numbers, we will first have to write them as a percentage as shown.

Given the number below

10/8, 1.2, 0.556, 0.8%

Convert to percentage

10/8 = 125%

1.2 = 120%

0.556 = 55.6%

0.8%

Hence the order from least to greatest is 0<u>.8%, 0.556, 1.2 and 10/8</u>
