A triangle where one angle measures 90 degrees and another angle measures 100 degrees because a triangle has three angles that add up to 180 degrees and when you add these two together it’s already over 180.
Answer:
745.5
Step-by-step explanation:
To answer this question we need to find the perimeter and multiply it by three. To do that we can start by adding 85 yards plus 85 yards for both sides of the rectangle which equals 170. Then we need to add the circumference of the semicircles. To do that we can use the formula C = 2(3.14)r. for that we need to find the radius which is the diameter divided by 2 which is 12.5. Then we can plug that into the formula to get C=(2)(3.14)(12.5). After solving that we get 78.5 which we can add to 170 to get the perimeter which is 248.5 . However we are NOT done since jasmine is running 3 laps we need to multiply 248.5 by 3 to get an answer of 745.5.
If we plug x = 3 into the equation we have
7(3) - 7 = 14
and
2(3) + 8 = 14
So the answer is C
