Law of sines and cosines word problem
Answer:
AC = 0.47 mi
BC = 0.51 mi
Step-by-step explanation:
Notice that we are in the case of an acute triangle for which we know two angles ( < A = 63 and < B = 56) and one side (AB = 0.5).
We can find the measure of the third angle using the property of addition of three internal angles of a triangle:
< A + < B + < C = 180
63 + 56 + < C = 180 degrees
< C = 180 - 63 - 56 = 61 degrees.
Now we use the law of sines to find the length of sides AC and BC:
[tex]\frac{0.5}{sin(61)} =\frac{AC}{sin(56)}\\AC=\frac{0.5*sin(56)}{sin(61)} \\AC\approx 0.4739\,\,\,mi[/tex]
which can be rounded to two decimals as:
AC = 0.47mi
For side BC we use:
[tex]\frac{0.5}{sin(61)} =\frac{BC}{sin(63)}\\BC=\frac{0.5*sin(63)}{sin(61)} \\BC\approx 0.509\,\,\,mi[/tex]
which can be rounded to two decimals as:
BC = 0.51 mi

Answer: XY=21 YZ=29
Step-by-step explanation: okay so the entire line (XZ) is equal to 50, and its made up of a and a + 8. So you can make an equation out of that.
a+a+8=50
2a+8=50
2a=42
a=21
then you just have XY equal 21, and YZ equal 21+8 or 29.
Answer:
XY = 21
YZ = 29
Step-by-step explanation:
XZ = 50
XY = a
YZ = a + 8
XY + YZ = XZ
a + (a + 8) = 50
2a + 8 = 50
2a = 50 - 8
2a = 42
a = 42 ÷ 2
= 21

Find 162.5% of 200
(HURRRY PLEASE)
Answer:
325
have a nice day and can I have brainliest?
Answer:
325.
Step-by-step explanation:
200/x=100/162.5
(200/x)*x=(100/162.5)*x - we multiply both sides of the equation by x
200=0.61538461538462*x - we divide both sides of the equation by (0.61538461538462) to get x
200/0.61538461538462=x
325=x
x=325

I'M KINDA SURE
Step-by-step explanation:
Those images aren't good enough, I can't really get a good look. Basically, if there are nine little lines between each whole number, then each little line represents a tenth of a whole number, or 0.1. If there are four little lines between each whole number, then each little lines is 0.2. So, you just count up from the whole number below the value. For A, start at 1.0 and count up, each little line is 0.1 (if there are nine lines between each whole number), and figure out where A lies. Hope it helped, wish I could give a definite answer.

mother is m years old,and she is 4 times old as her daughter.How much older is mother then daughter.
Answer:
The mother is 3d older than the daughter
Step-by-step explanation:
Given
Represent the mother's age with m
and
The daughter's age with d
Required
Determine how much older is the mother
First, we need to calculate the mother's age
[tex]m = 4 * d[/tex]
[tex]m = 4d[/tex]
Next, we calculate their age difference
[tex]Age\ Difference = m - d[/tex]
Substitute 4d for m, we have:
[tex]Age\ Difference = 4d - d[/tex]
[tex]Age\ Difference = 3d[/tex]
Hence, the mother is 3d older than the daughter
