First you need to isolate the term X variable on one side of the equation by either subtracting to combine like terms
Answer:
110 degrees
Step-by-step explanation:
The 23x + 1 angle is supplementary (adds to 180) to 36x + 2 so that means
23x + 1 + 36x + 2 = 180
Which in turn means : x = 3
Which then means : Bold angle = 36 * 3 + 2 = 110
Step-by-step explanation:
(1 - cos²A) (1 + tan²A) = tan²A
(sin²A)(sec²A) = tan²A
(sin²A)(1/cos²A) = tan²A
(sin²A)/(cos²A) = tan²A
tan²A = tan²A → <u>Proved</u>
Answer:
1/9
Step-by-step explanation:
x^-2
We know that a^-2 = 1/ a^2
1/x^2
Let x = -3
1/ (-3)^2
1/9
