How to find a measure of angle A?

Mathematics
1 answer:
vodomira [7]4 years ago

To find the measure of the smallest angle of the triangle, we multiply 4 times 10. So, 4 x 10 = 40. Remember, the sum of the angles of a triangle is 180 degrees. Just take what you are given in a problem and try to determine what will make the final angle add up to 180 degrees. Hope this helps even though it probably won’t :D

My name is Ann [436]

Answer:

h=-16t^2+ 30t+4.

Step-by-step explanation:

For the table you just plug in the <em>t</em> (time) into the equation. So for the first one we have 0 seconds. So you plug in the 0 where it says <em>t</em>. So the equation becomes h=-16*0^2+30*0+4. Which gives us 4 <em>h</em>(height). Then you keep pluging in the time into the equation.

Time <em>t </em>in seconds       0        .5       1         1.5      2

Height <em>h </em>in feet           4        15      18       13      0

5miles = 8km. How many km in 80miles?
Zina [86]

Answer:

128

Step-by-step explanation:

Set this up as a proportion with miles on the top and km on the bottom:

\frac{mi}{km}:\frac{5}{8}

If we want to know how many km are in 80 miles, we put the variable with the km stuff on the bottom and 80 on top and cross multiply to solve for the variable:

\frac{mi}{km}:\frac{5}{8}=\frac{80}{x} so

5x = 640 and

x = 128

That means that 80 miles is equivalent to 128 km
