Ответ:
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.
