1) Identify the sides 2) Identify the trig ratio that you need
3) On your calculator input to find the length AB

Please check the explanation.

Step-by-step explanation:

Given

The angle Ф = 42°

The hypotenuse = 15 cm

To determine

The length AB = ?

Using the trigonometric ratio

cos Ф = adjacent / hypotenuse

In our case:

so substituting Ф = 42°, adjacent = AB, hypotenuse 15 in the trigonometric ratio

cos Ф = adjacent / hypotenuse

cos 42° = AB / 15

AB = 15 × cos 42°

AB = 11.14 cm

Therefore, the length of the side AB = 11.14 cm

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
