Answer:
$20.70
Step-by-step explanation:
$9.20 x 2 1/4 (lbs) = $20.70
305-35=270 (SA of 3 triangular faces)
270/3=90 (area of one face)
A=.5BH
90=.5(9)H
90=4.5H
H=20 in
Answer:
m∠2 = 113º
m∠3 = 67º
Step-by-step explanation:
m∠2 is supplementary to m∠1, meaning if you add them to m∠1, you will get 180º.
m∠2 + m∠1 = 180º.
m∠2 + 67º = 180º
m∠2 = 113º
m∠1 and m∠3 are vertical angles and are therefore the same.
That looks right if all you were doing was finding how many more you needed than it should be good
