You would divide both sides by the same non-zero constant
6) Being that x=0 , angle R will be equal to 65.
7) Being that x=2, angle N will be equal to 116 .
Note that : adjacent angles (the ones next to each other) adds up to 180 & opposite angles are congruent meaning that they equal each other.
Y=x-2
-2 is the y-intercept. the slope is 1. Plug in the info for the slope-intercept form which is y=mx+b
Answer:
x = 120°
Step-by-step explanation:
We are given;
sec²x + 4secx = -4
Rearranging gives;
sec²x + 4secx + 4 = 0
Factorizing the left hand side gives;
(sec x + 2)(sec x + 2) = 0
This means that;
(sec x + 2) = 0
From trigonometry, we know that sec x = 1/cos x
Thus;
(1/cos x) + 2 = 0
1/cos x = -2
cos x = -1/2
cos x = -0.5
x = cos^(-1) -0.5
x = 120°
