Answer:

  90.1 m

Step-by-step explanation:

The length of the shortcut is the hypotenuse of a right triangle with side lengths 30 and 85. That length can be found using the Pythagorean theorem.

  PQ² = 30² +85² = 8125

  PQ = √8125 ≈ 90.1

The length of the shortcut is 90.1 meters.

Simplify : 9 Sin A +3 cosec A + 10sin A- 13 CosecA<br>​
Shtirlitz [24]

Answer:

19Sin A - (10/sin A)

Step-by-step explanation:

We want to simplify;

9Sin A + 3cosec A + 10sin A - 13Cosec A

Let's rearrange it for ease of addition;

(9Sin A + 10sin A) + (3cosec A - 13Cosec A)

>> 19Sin A - 10cosec A

Now, from trigonometric ratios, we know that; Cosec A = 1/Sin A

Thus; 10cosec A = 10/sin A

Thus, we now have;

19Sin A - (10/sin A)
