Answer:
x = 40
Step-by-step explanation:
The angles add to 180 degrees
30+110 +x = 180
Combine like terms
140 +x = 180
Subtract 140 from each side
140+x-140 =180-140
x = 40
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.
