Answer:

x = 70 degrees,  y = 35 degrees.

Step-by-step explanation:

The angle marked  x  is a central angle, so its measure is the <u>same</u> as the measure of the intercepted arc.

The angle marked  y  is an inscribed angle, so its measure is <u>half</u> the measure of the intercepted arc.

Solve for z: 11=6|-2z| -5
skad [1K]

Answer:

the roots are {-4/3, 4/3}

Step-by-step explanation:

Begin the solution of 11=6|-2z| -5 by adding 5 to both sides:

11=6|-2z| -5 becomes 16 = 6|-2z|.

Dividing both sides by 12 yields

16/12 = |-z|

There are two cases here:  first, that one in which z is positive and second the one in which z is negative.

If z is positive, 4/3 = -z, and so z = -4/3, and:

If z is negative, 4/3 = z

Thus the roots are {-4/3, 4/3}
