Ok so
area=1/2 times base times height
lets say base and height=3 for one triangle and
base and height=6 for another
area1=1/2 times 3 times 3=9/2
area2=1/2 tmes 6 times 6=18
areas are
9/2 to 18=9:36=1:4
3:6=1:2
is 1:2=1:4? no
ratio is 1:4
if interior angle is 170, subtract 170 from 180 to find exterior angle:
180-170 = 10 = exterior angle
the sum of exterior angles is 360 so divide by exterior angle to find sides:
360 /10 = 36 sides
Answer:
She earned $60
Step-by-step explanation:
Since she had 20 dollars remaining from may, she earned the rest of the money in june so:
80-20=60
Answer:
33
Step-by-step explanation:
49-15=34
34/17=2
For this sequence, you can write this function:
f(x)=15+2(x-1)
Check:
f(18)=15+2(18-1)
f(18)=15+2(17)
f(18)=15+34
f(18)=49
So:
f(10)=15+2(10-1)
f(10)=15+2(9)
f(10)=15+18
f(10)=33
