Answer:
SV is 5
Step-by-step explanation:
SV and TU must be equal, so x+3=4x-3 x=4x-6 x=2
SV=2+3
SV=5
It is either the Second or third one
Answer:
I'm going to also give you how to get the answer... not just the answer.. you will need to know this for a test :/ so learn it :P
Step-by-step explanation:
Sin(30)=12
to remember what Sin and Cos at those speacial angles in degrees are.. just use this Sin(degrees)
Sin(0) = 0/2 =0
Sin(30)= /2 = 1/2
Sing(45) = /2 = /2
Sin(60)=/2 = /2
Sin(90)=/2 = 1
Cos is exactly the same but counts backwards from 90°
Cos(90) = 0/2 =0
Cos(60) = /2 = 1/2
Cos(45) = /2 = /2
Cos(30) = /2 = /2
Cos(0) =/2 = 1
note that the numerators just count from 0,1,2,3,4 , see? you can remember sin and cos now :) since you can count to 4 :P
Sin(30) =12
1/2 =12 while that statement makes no sense.... obviously 1/2 isn't equal to 12 but.. what's being said is that the angle of 30° gives you a side that is 12 units long.
so looking at what I wrote above.. which angle in degrees matches Sin when you look at Cos?
Sin(30)= 1/2 and Cos(60) also = 1/2 huh
sooo β = 60 °
got it? :/
Answer:
If you see the top and bottom of the figures are getting smaller by two, so for A its getting smaller by two, and for B it will just be a solid set of four lines
Step-by-step explanation: make sure you put it in you own words
