The period is equal to 2pi/n, where n is the coefficient of t. In this case pi/2. Therefore the period in this example is 4. Frequency is equal to 1/period. Hence the frequency for this problem is 1/4

RSM HOMEWORK HELP!!!
Gnesinka [82]

Answer:

Step-by-step explanation:

∠CAB = 33       {alternate interior angles}

5x = 33 + 2x    { exterior angle equals sum of opposite interior angles}

5x - 2x = 33

3x = 33

x = 33/3

x = 11

∠B = 2x = 2* 11 = 22

∠ECB = 5x = 5*11 = 55
