Answer:
5.75 ft on each side
Step-by-step explanation:
6ft*8ft=48ft
71ft-48ft=23ft
23-4=5.75ft
Angles B and C are both supplimentary angles with the numbers they are closest to. The sum of two supplimentary angles is always 180 degree. Therefore:
B + 45 = 180
B = 135
C + 105 = 180
C = 75
We now know two out of three of the angles for the inside of the triangle. The sum of the interior angles of a triangle is always 180. Therefore, we can solve for A.
A + 75 + 45 = 180
A = 60
Therefore A = 60, B = 135 and C = 75.
Add all of them up and you get D. Can you plz put brainliest answer I'm trying to rank up
Answer:
720
Step-by-step explanation:
Since there are six coordinates, the polygon must be a hexagon.
Sum of angles in a polygon= (n-2)×180
= (6-2) × 180
= 720
Answer:
42 home team and 33 away team fans attended the game.
Step-by-step explanation:
Let
- h denote the number of home team fans
- a denote the number of away team fans.
Since 75 people attended a baseball game and everyone there was a fan of either the home team or the away team; we have
(1) h+a=75.
Since the number of home team fans was 90 less than 4 times the number of away team fans, we have
(2) h=4×a-90
In (1) lets put 4×a-90 instead of h, since h=4×a-90, we have then
4×a-90+a=75
4×a+a=75+90
5×a=165 and finally
a=
We know that h+a=75, if a=33 then h=42
