<span>A regular octagon is a closed figure with sides of the same length and internal angles of the same size. so if it is rotated 360 degrees it should coincide with its preimage after every 45 degrees. So 360/45= 8 times</span>
Suppose a mango cost x dollar and a apple cost y dollar
there will be an binary system of equation
8*x+3*y=18
3*x+5*y=14.5
so soultions have to x=48/31 y=16/31
Step-by-step explanation:
x+100°=180°{being straight angle}
x=180-100
x=80°
again,
45°+x+y=180°{sum of angle of triangle}
45+80+y=180
y=180-125°
y=55°
hope it helps.
115 would be your answer because 180-65=115
Answer:
63 pages
Step-by-step explanation:
I AM NOT SURE THIS IS CORRECT. I WILL EXPLAIN MY REASONING THOUGH.
Take 210 (pages) and multiply that by 30% or 0.3 that will give you 63. This means that 30% of the book is 63 pages
