Hope it helps....!!!!!
Step-by-step explanation:
AB = c = 38
BC = a = 29
AC = b
Angle ABC = 63 degrees
Solving for AC "b":
Cosine rule: c^2 = a^2 * b^2 -2ab * cos C
38^2 = 29^2 * b^2 - (2* 29) * b * (cos 38)
1444 = 841 * b^2 - 58 * b * 0.955
(1444 + 58)/0.955 = b^2 * b
1572.77486911 = b^3
11.62935 = b
11.63 = b (rounded to two decimal places)
Now solving for angle A:
Sine rule: a/sinA = b/sinB
29/sinA = 11.63/sin(63)
sinA/29 = sin(63)/11.63
sin A = (sin(63)/11.63) * 29
sin A = 0.41731
A = sin^-1 (0.41731)
A = 24 degrees 39 minutes 53 seconds
Now solving for angle C:
Sine rule: c/sinC = b/sinB
38/sinC = 11.63/sin(63)
sinC/38 = sin(63)/11.63
sin C = (sin(63)/11.63) * 38
sin C = 0.54682
C = sin^-1 (0.54682)
C = 33 degrees 8 minutes 56 seconds
Direct variation means their ratio is a constant
x/y is 9/45=1/5
so when x=2, y=5*2=10
A - b is NOT always natural. Eg 4 - 7 = -3 therefore not in the natural number set.
ab is always natural
a/b is NOT always natural. Eg 4/7
So the answer to the question is (b) only II must be a natural number answer.
The first thing you should do when solving equations is to check for like terms. If you do find any like terms, combine them.
6d - 3d + 2d - 6 = 4d
On the left-hand side, we can combine the d terms.
6d - 3d + 2d - 6 = 4d
5d - 6 = 4d
The next is to get the variable we're trying to solve for all alone. To do that, we'll have to add / subtract / multiply / divide on both sides of the equation.
5d - 6 = 4d
-6 = -d
Here I subtract 5d from each side of the equation which resulted the d variable almost being all alone. It's being multiplied by a -1, which is the reason why it has a negative sign. To get rid of the -1, divide both sides by -1.
-6 = -d
-6 / -1 = -d / -1
6 = d
So, d is equal to 6.
