Answer:
Step-by-step explanation:
This triangle is a polygon. By definition, all the exterior angles of ANY polygon add up to equal 360 degrees. So we add up all the exterior angles and solve for x. That's the first step.
7x - 2 + 9x - 31 + 4x + 33 = 360
Combining like terms gives us
20x + 0 = 360 or simply
20x = 360 so
x = 18
In order to find the value of the angle exterior to angle C, we sub 18 in for x:
7(18) - 2 = 124
4/12 plus 9/12 =15/12=1 3/12 = 1 1/4
Answer:
The equivalent trigonometric ratio in Quadrant I is 
Step-by-step explanation:
The terminal side of 
is in the 3rd quadrant.
The principal angle is 
In other words, the terminal side of makes an acute angle of radian with the positive x-axis. Acute angles are in the first quadrant.
Since the cosine ratio is negative in the 3rd quadrant,
2x+4y=8;3x+4y=16<span>. is the answer
