Step-by-step explanation:

By Linear Pair Theorem,

110⁰ + 5x⁰ = 180⁰

5x⁰ = 70⁰ ------- (1)

x⁰ = 14⁰

We know that adding the angles of the triangle lying on the same side, equals the opposite exterior angle, i.e.,

5x⁰ + 40⁰ = 2y⁰

From 1,

70⁰ + 40⁰ = 2y⁰

110⁰ = 2y⁰

y⁰ = 55⁰

Answer: (a) IV (b) positive (c) \frac{\pi}{4} (d) C (e) \sqrt{2}

<u>Step-by-step explanation:</u>

a) \frac{15\pi}{4} - \frac{8\pi}{4} = \frac{7\pi}{4}, which is located in Quadrant IV <em>per the Unit Circle.  </em>

b) sec is \frac{1}{cos}. Cos is the x-coordinate.  The x-coordinate inQuadrant IV is positive.

c) the reference angle is the angle from \frac{7\pi}{4} to 2π = \frac{\pi}{4}

d) since the angle is below the x-axis and the reference angle is\frac{\pi}{4}, then the angle is equal to -sec(\frac{\pi}{4})

e) sec = \frac{1}{cos}   ⇒   sec \frac{7\pi}{4} = \frac{2}{\sqrt{2} } = \frac{2}{\sqrt{2} }(\frac{\sqrt{2}} {\sqrt{2}}) = \frac{2\sqrt{2} }{2} = \sqrt{2}

Answer: (a) \frac{3\pi}{2} (b) (0, -1) (c) A (d) -1

<u>Step-by-step explanation:</u>

a) \frac{11\pi}{2} - \frac{4\pi}{2} = \frac{7\pi}{2} - \frac{11\pi}{2} = \frac{3\pi}{2}

b) \frac{3\pi}{2} is on the Unit Circle at (0, -1)

c) sin = \frac{opposite}{hypotenuse} which equals \frac{y}{r} on the Unit Circle.

d) sin is the y-coordinate. sin (\frac{3\pi}{2}) = -1

Which equation represents the line shown in the graph below?
likoan [24]

The answer is y=2x+5


To get it use point slope by taking two points and solving .


Slope formula


M= y2-y1/x2-x1


With two points


(0,5)(-5,-5)


M= -5-5/-5-0

M= -10/-5

M=2


2 is slope


Now get one of the points

(0,5) And slope to create equation y=mx+b . Now find b


5=2(0)+b

5=b


So now you can put it all together


Y= 2x+5

Can someone please help this is due at 9
likoan [24]

Answer:

70

Step-by-step explanation:

We have the final part 4x/40 = 7. We can simplify this to x/10 = 7 by dividing the numerator and the denominator by 4. We then multiply both sides by 10 to get x = 70
