Answer:
the seventh grader because the eighth graders got 58 which is more than 50 so the 7th grader would get the pts
Step-by-step explanation:

Problem 7
This triangle is an equilateral triangle. All sides are the same length (some unknown number which we don't care about). All angles are the same measure each 60 degrees. Set this expression equal to 60 and solve for x
25x - 15 = 60
25x - 15+15 = 60+15 ... add 15 to both sides
25x = 75
25x/25 = 75/25 .... divide both sides by 25
x = 3 which is the answer we want

Problem 8
For this problem, I've decided to break up the work into separate image files to show how I did the steps. Otherwise, it might be really cluttered to have everything typed here on the same page.
To get the coordinates of point E, check out the image labeled "figure 1". For point G, look at "figure 2".
For proof that EG is parallel to BC, look at "figure 3"
For proof that segment EG is half the length of segment BC, look at "figure 4"
Finally, I've drawn on the diagram to visually show what it all looks like as a summary in "figure 5"
Answer:
bottom. one is correct I know it for a fact
Davie will take 80/20= 4 hours to finish the tour. Horatio has only 2 and 1/2 hours to cover the same 80 miles. (80)/(2.5)= 32 miles per hour.
Answer:
34.0 m
Step-by-step explanation:
The total angle sum in a triangle should be 180° hence the missing angle will be given by
180°-145°-28°=7°
Using sine rule

By substituting 160 for m, 145° for M and 7° for L then

Making l the subject then
