Suppose that angle P = 3x + 14 and angle Q = 3x - 27. If these angles are supplementary, angle Q would need to be ___ degrees.

adelina 88 [10]

Answer:

Q = 69.5 degrees

Step-by-step explanation:

3x + 14 + 3x - 27 = 180

6x - 13 = 180

6x = 193

x = 32.1667

Q = 3(32.1667) - 27

Q = 69.5

Four angles must add up to 360.

∠A+∠B+∠C+∠D=360 (5/2x+30)+(7/2x+40)+(9/2x+10)+(5/2x+20)=360 26/2x + 100 = 360 13x = 260 x = 20. To solve for ∠C, plug x back in: ∠C = 9/2x+10 = 9/2*20+10 = 100

AXYZ is rotated 180°.<br> What are the coordinates of point X'?

vredina [299]

<h3>Answer: (4, -1)</h3>

Reason:

When rotating a point 180 degrees around the origin, you use the rule

$(x,y) \to (-x,-y)$

We flip the sign of each coordinate from positive to negative or vice versa.

The point X is at the location (-4, 1). Rotating this 180 degrees will get us to X'(4, -1)
