8 0

Sea level is 0

robert dives 40 ft.....-40
he then rises 23 ft.....-40 + 23 = -17
he then dives 19 ft to meet Sam....-17 - 19 = -36
together they rise 31 ft...-36 + 31 = - 5

they are 5 ft below sea level <==

3x - 6x + 2 > 65<br> Mathematic

LenKa [72]

3x - 6x + 2 > 65

Combine like terms.

-3x + 2 > 65

Subtract 2 from both sides.

-3x > 62

Divide both sides by -3

x < -62/3

WXYZ is a parallelogram. Find the measure of angle Z

Delvig [45]

Given:

The figure of a parallelogram.

To find:

The measure of angle Z.

Solution:

We know that, the consecutive interior angles of a parallelogram are supplementary angles, it means there sum is 180 degrees.

In the given figure angle W and angle Z are supplementary angle. So,

$m\angle W+m\angle Z=180^\circ$

$(18b-11)^\circ+(9b+2)^\circ=180^\circ$

$(27b-9)^\circ=180^\circ$

$(27b-9)=180$

Adding 9 on both sides, we get

$27b=180+9$

$27b=189$

$b=\dfrac{189}{27}$

$b=7$

Now,

$m\angle Z=(9b+2)^\circ$

$m\angle Z=(9(7)+2)^\circ$

$m\angle Z=(63+2)^\circ$

$m\angle Z=65^\circ$

Therefore, the correct option is C.
