Angles 5 and 7 are vertically opposite angles.
angle 5=angle 7
angles 4 and angle 4 are co interior and are supplementary angles
implies that angles 4 and 7 sum up to 180 degrees
angle 4 = 180 -114 =66 degrees

Angle T had a measure between 0 and 360 and is coterminal with -170 angle. What is the measure of angle T?

Alika [10]

Answer: The answer is 190°.

Step-by-step explanation: We are to find the measure of ∠T which lies between 0° and 360° and is co-terminal with an angle of measure -170°.

We know that two angles are said to be co-terminal if one is obtained from the other by either adding or subtracting 360°.

So, angles which are co-terminal with -170° are

-170° + 360° = 190°, -170° - 360° = 530°, etc.

Since 190° lies between 0° and 360°, so measure of ∠T is 190°.

Thus, the answer is 190°.

Answer:

$3 {x}^{2} - 5x + 4x = 3 {x}^{2} - 5 {x}^{2} + 9x \\ 3 {x}^{2} - x = - 2 {x}^{2} + 9x \\ 3 {x}^{2} + 2{x}^{2} = 9x + x \\5 {x}^{2} = 10x \\ 5x = 10 \\ x = \frac{10}{5} = 2 \\ x = 2 \\ thank \: you$

Review the graph of complex number z.

Answer:

$6\sqrt{2} (\cos(135^{\circ})+i\sin(135^{\circ}))$

Step-by-step explanation:

The angle to the point in the second quadrant is measured from the positive real axis (the x-axis). Second quadrant angles are between 90° and 180°, leaving the 135° choices as the only ones that make sense.

The magnitude of z is the root of the sum of the squares of its components:

|z| = √((-6)^2 +6^2) = 6√2

So, the polar form of z is ...

$\boxed{6\sqrt{2} (\cos(135^{\circ})+i\sin(135^{\circ}))}$
