Please help me and can you show full working

1. a = 491.49 cm,

2. b = 2.875 m,

3. c = 130.737 m,

4. d = 30.464°, and

5. e = 13.940 ° (sixth figure not visible).

Step-by-step explanation:

Step 1:

The three basic formula needed to solve these questions are:

To calculate, the angles we use

Step 2:

The triangle's angle = 85°, opposite side = a cm and adjacent side = 43 cm. So

,

Step 3:

The triangle's angle = 49°, opposite side = b m and adjacent side = 2.5 m. So

Step 4:

The triangle's angle = 44°, hypotenuse = c m and adjacent side = 94 m. So

Step 5:

The triangle's angle = d°, opposite side = 1.8 m and hypotenuse = 35 cm = 3.55 m.

Step 6:

The triangle's angle = e°, opposite side = 15.9 m and hypotenuse = 66 cm = 3.55 m.

hi how are you doing today, if you need just ask me.
