(urgent) someone i do not get these questions and i only get one try to insert the correct answer. (if will mark your answer as brainliest)

see explanation

Step-by-step explanation:

1

Using right ΔBCD and the tangent ratio to solve for BC

tan40° =

Multiply both sides by 20

20 × tan40° = BC

BC ≈ 16.8

----------------------------------------------------

2

Using right ΔABC and the cosine ratio to solve for AB

cos30° = =

Multiply both sides by AB

AB cos30° = 30 ( divide both sides by cos30° )

AB = ≈ 34.6

------------------------------------------------------------

3

Using the tangent ratio

tanA = = , hence

A = ( ) ≈ 22.6°

------------------------------------------------------------------

4

Using the sine ratio

sin58° =

Multiply both sides by x

x sin58° = 4 ( divide both sides by sin58° )

x = ≈ 4.7

-------------------------------------------------------------

5

Any of the 3 trig ratios may be used here since all 3 sides are given.

Using the tangent ratio

tan58° =

Multiply both sides by x

x tan58° = 4 ( divide both sides by tan58° )

x = ≈ 2.5

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
