let the line between 2 tria be y
sin 60/8√2 = sin 90/y
y=13.06
sin 45/13.06 = sin 90/x
x=18.46
Not it doesn’t form a right angle because if you add it all together it makes it 54
N! means multiply the number by every number less than n
example 5! means 5 x 4 x 3 x 2 x 1
Answer:
let
i= simple interest
p= principal
t= time
r=rate
data given
p=$720
r=4.25%
t= 3months
i=?
from the formula
i=prt
i=$720×(4.25/100)×3
i=$720×0.0425×3
i=$91.8
therefore simple interest for 3 months is $91.8
