Answer:

103

Step-by-step explanation:

To solve this you first have to find the complement to he 110 degree angle (z). You do this by subtracting 180-110 to get z=70 degrees. Next, because its a four sided figure you know the total angle sum should equal 360. Therefore, 360-100-87-70=angle y. Angle y= 103 degrees. Hope this helps

At the beginning of my bike ride I feel good, so I can travel 20 miles per hour. Later, I get tired and travel only 12 miles per
Vesnalui [34]

Answer: 3\dfrac{1}{4} hours

Step-by-step explanation:

Let x be the time ( in hours ) you feel good and y be the time ( in hours ) that you get tired.

As per given , we have

x+y= 8

Since : Distance = Speed\times Time

So , we have

20x+12y=122

According to the given question , we have the following system of equations ,

x+y= 8--------(1)\\\\20x+12y=122------------------(2)

Multiply 12 on both sides of equation (1) , we get

12x+12y=96------------(3)

Eliminate equation (3) from (2) , we get

8x=26\\\\\Rightarrow\ x=\dfrac{13}{4}=3\dfrac{1}{4}

Hence, you felt 3\dfrac{1}{4} hours good.

Which equation would you use to find how high the bird is flying?
damaskus [11]

Answer:

The first one

Step-by-step explanation:

An easy way is SOH CAH TOA

SOH is that you use sine if you there is the opposite (in this case the question mark) and hypotenuse (the diagonal line)

CAH is that you use cosine for the adjacent side (1100) and the hypotenuse.

TOA is using tangent for the opposite and adjacent side.

To fine the question mark, you would use tangent. And plug in the given (1100 for the adjacent). So tan45 = x/1100.

If you need more help or clarification, let me know!
