Answer:

Anticlockwise 60°

Step-by-step explanation:

Let my starting point be 0°

Turning to the right(clockwise)40° = 0° + 40° = 40°

I am now at 40° to the right of my starting point.

Turning to the left(anticlockwise) 70° = 40° - 70° = -30°

I am now 30° to the left of my starting point.

Turning to the right 90° = -30° + 90° = 60°

I am 60° to the right of my starting point.

To go back to the startoing point(0°), I should go to the left(anticlockwise) by 60°

This is a change of -60°

Step-by-step explanation:

Given :-

sin² a/2 - sin a/2 + 1/4

To find :-

Solving :-

sin² a/2 - sin a/2 + 1/4 = (sin a/2 - 1/2)² = 0

sin a/2 - 1/2 = 0

sin a/2 = 1/2

a/2 = 30°

Nitella [24]

Answer:

Step-by-step explanation:

Apply the value of x into the expressions:

3(5) - 10 = 15 - 10

= 5

5² - 15 = 25 - 15

= 10

5(5) - 21 = 25 - 21

= 4

5 + 10 - 8 = 15 - 8

= 7
