Since all triangle's angle's values add up 180 degrees, this means we have to make sure to angles add up to 180.

A. 75 + 35 = 110. 180 - 110 = 70 degrees.

B. This triangle is isosceles meaning 2 of its sides is the same length. In this case, the two sides add up to 140 (meaning they are both 70 degrees). 180 - 140 =  40 degrees.

C. I sadly don't know how to solve it.

D. This is another isosceles triangle. 180 - 36 = 144.

Answer:

For  

x

We can next plot the two points on the coordinate plane:

graph{((x-6)^2+y^2-0.035)((x-4)^2+(y-2)^2-0.035)=0 [-10, 10, -5, 5]}

Now, we can draw a straight line through the two points to graph the line:

graph{(y+x-6)((x-6)^2+y^2-0.035)((x-4)^2+(y-2)^2-0.035)=0 [-10, 10, -5, 5]}

How can you find a unit rate when given a rate?
ivanzaharov [21]
It depends on the problem really. One example is that you drive 10 miles in 2 hours. So you divide the distance over time to get 10/2 = 5. This means you drove 5 miles per hour (mph). The unit rate for this example is 5 mph.
