A line that would appear like this ( / ) on a graph would have a positive slope because the coordinates that the line passes through are increasing from left to right.
Trigonometric functions which are related by having the same value at complementary angles are called cofunctions. Cofunctions of complementary angles are equal.
A. csc 20' = csc(90-70)=sec 70
B. cos 87' = cos (90-3)=sin 3'
C. csc 40' = csc(90-50) =sec50'
D. tan 15' = tan(90-75)= cot 75'
Among all the option c is not correct.
Option C is false.
Answer:
109
Step-by-step explanation:
81-19 is 62. if you add 109 then you could do 109-19 is 90
Answer:
option C
A number line with a closed circle on
and shading to the left
Step-by-step explanation:
we have

solve for x

Subtract
both sides


Divide by
both sides
--------> is equivalent to 
The solution is the interval--------> [9,∞)
All real numbers greater than or equal to 
A number line with a closed circle on
and shading to the right
