Answer:
B
Step-by-step explanation:
1. A reflection across the origin has a rule

2. A translation 9 units to the left and 7 units down has a rule

Then the rule for a reflection across the origin followed by a translation 9 units to the left and 7 units down is

This means that the point with coordinates (x,y) has the image with coordinates (x',y')=(-x-9,-y-7).

Acronym to remember the 3 basic trigonomic functions:
Soh - Cah - Toa
opposite
sin = --------------------
hypotenuse
adjacent
cos = -------------------
hypotenuse
opposite
tan = -----------------
adjacent
In your case, you can set up a sine trigonomic function, like this:
Sin 48 = 10 (adjacent)
-----
x (hypotenuse)
10
(x) Sin 48 = ------ (x)
x
(x) Sin 48 = 10
-------------- -------------
Sin 48 Sin 48
Plug in 10(sin)(48) into a calculator.
x = 7.43
I just realized that you didn't ask me to find the answer, but now you will know even more than you need to :D
Answer:
Angle G = 76 degrees
Step-by-step explanation:
66 + 2x + x = 180
66 + 3x = 180
3x = 114
x = 38
2(38) = 76
Answer:
0
Step-by-step explanation:
To find the slope of a line, we uses y2-y1/x2-x1:
y2-y1/x2-x1
1-1/7+2
0/9
0
The slope of the line is 0.
