31 degrees, 31 degrees, 118 degrees
Step-by-step explanation:
Step 1 :
Let x be the measure of 2 angles of the given isosceles triangle with same measure
Let y be the measure of 3rd angle
So we have x + x + y = 180
Step 2 :
Given that the measure of 3rd angle of triangle is 25° more than three times the measure of either of the other two angles
So we have , y = 3 x + 25
Step 3:
Substituting for y in the first equation we have,
x + x + 3 x + 25 = 180
=> 5 x + 25 = 180
=> 5 x = 180-25 = 155
=> x = 155/5 = 31
Hence the 2 angles of the triangle are 31 degrees.
Step 4:
we have y = 3 x + 25
=> y = 3 * 31 + 25 = 118
Hence the 3rd angle of given triangle is 118 degrees
Answer:
17 X 8 = 136^
area of a triangle
0.5 X b X h
0.5 X 8 X 17 = 68 cm^
136 - 68 = 68 cm^
total shaded area = 68 cm^
Answer:
18/28, or percentage wise, approximately 64.2%
Step-by-step explanation:
Take the seniors and divide it by the total # of students, and you got your probability!
We'd have to simply divide the total amount of hours by the total amount of episodes. This would be 10.5 / 14 = 0.75
So now, let's check if this is correct by multiplying 0.75 * 14 which should give us 10.5.
So the answer would be: 0.75 hours per episode.
