I did some math and i got this
x = -2
Answer:
2x+2
Step-by-step explanation:
of symbols, representing a value, o relation. example 2+2=4
Answer: 39.2Check out the attached image
============================================================
Explanation:
Draw out the triangle or use the diagram provided by your teacher. It should look something similar to what I've attached.
Let m = length of side XZ
We are given that
angle Y = 75 degrees
angle Z = 67 degrees
which are the green angles shown in the diagram
Use the fact that the three angles (X,Y,Z) add to 180 degrees to find angle X
X+Y+Z = 180
X+75+67 = 180
X+142 = 180
X+142-142 = 180-142
X = 38
Now use the law of sines to find m
sin(X)/YZ = sin(Y)/XZ
sin(38)/25 = sin(75)/m
m*sin(38) = 25*sin(75)
m = 25*sin(75)/sin(38)
m = 39.22309 <<<--- make sure your calculator is in degree mode
m =
39.2So
XZ is roughly 39.2 feet in length
The answer is B, 3/4 miles to 1/2 inch which means 1.5 miles to 1 inch, because in the second map, the inches were divided by 2, making the map smaller, therefore we should double the scale to get the same measurments
