Answer:
<u>-12</u>
Step-by-step explanation:
12 - 15 = -3
4 ( -3 )
= -12
Go-rite: 12.75 / 3 = 4.25 (go-rite is $4.25 per pound)
Green zone: $4.50
4.50- 4.25= 0.25
Go-rite is cheaper by .25
Answer:
You have to give us the other expressions :)
Step-by-step explanation:
AE = AC = 4
m<CAB = 60 (equilateral triangle)
m<CAE = 90 (square)
m<BAE = 150 (= 60 + 90)
Triangle BAE is isosceles since AB = AE;
therefore, m<AEB = m<ABE.
m<AEB + m<ABE + m<BAE = 180
m<AEB + m< ABE + 150 = 180
m<AEB + m<AEB = 30
m<AEB = 15
In triangle ABE, we know AE = AB = 4;
we also know m<BAE = 150, and m<AEB = 15.
We can use the law of sines to find BE.
BE/(sin 150) = 4/(sin 15)
BE = (4 sin 150)/(sin 15)
BE = 7.727
Answer:
inverse of sin 1.6
or it can be written as sin^1 1.6
