20/29
21/20
20/29
21/29
20/21
Step-by-step explanation:
Use Soh Cah Toa for each, using the right equation for the right angle
e.g for sin(z) we use the opposite/adjacent for that angle
- the hypotenuse is the biggest size
- the opposite is the side opposite to the angle you are using
- the adjacent is the other side
The value of <em>d</em> is 7.5.
The key to solving equations is doing the inverse, or opposite, function/process.
For example, you subtract when d + 1 = 2:
d + 1 = 2
(d + 1) -1 = (2) - 1
d = 1
In the same way, you add values when you have a negative:
5.5 = -2 + d = d - 2
5.5 = d - 2
(5.5) + 2 = (d - 2) + 2
7.5 = d
Now if instead of adding 2, you subtract 2, the problem becomes:
5.5 = d - 2
(5.5) - 2 = (d - 2) - 2
3.5 = d - 4
This doesn't solve your problem, it just makes the value needed to be canceled out larger.
Thus d = 7.5 and you will add because the value is negative.
Answer:
32x
Step-by-step explanation:
C=2r
divide both sides by 2
c/2=r
c=2pir
divide by 2pi
c/(2pi)=r
Answer:
8/15 x 5/8 = 1/3
2/9 x 3/4 = 1/2
Step-by-step explanation:
multiply the numerators and denominators together.
8/15 x 5/8 = (8 x 5)/ (15 x 8)
40/120
Simplify by dividing by 40. (GCF)
1/3
----------------------------------------------------------------------------------------------------
multiply the numerators and denominators together.
2/9 x 3/4 = (2 x 3)/ (9 x 4)
6/36
Simplify by dividing by 6. (GCF)
1/2
