Answer:

-27/5 and 29

Step-by-step explanation:

First, simplify everything. You get 20x - _ * 5/9 + 9x = 3 + _ * x.

This is 29x - _ * 5/9 = 3 + _ * x.

The 2nd blank must be 29 because there is nothing else to alter it.

Using the same logic, the first blank is -27/5.

Trigonometry: 1) Work out the bearing from B to C. 2) Calculate the bearing of D from B

kakasveta [241]

Answer:

see below

Step-by-step explanation:

a bearing is the angle in degrees measured clockwise from north.

Triangle ABC is a right triangle

Tan C = opp side / hyp

tan C = AB / CA

tan C = 30/30

tan C = 1

taking the inverse tan

tan ^ -1 tan C = tan ^ -1 ( 1)

C = 45 degrees

This is 90+45 degrees from North

135 degrees from north

Tan B = opp side / hyp

tan B = AD/BA

tan B = 45/30

tan B = 3/2

taking the inverse tan

tan ^ -1 tan B = tan ^ -1 ( 3/2)

D = 56.30993247

Add 180 degrees

180+56.30993247

236.3099325 from north
