If we know that line AB is equal to line AD, then this means that ∠ADB has to be equal to ∠ABD in order to form a closed triangle. All angle measures of a triangle add up to 180°, so use the equation: 2(35) + x = 180.

70 + x = 180

Subtract 70 from both sides to isolate x:

180 - 70 = 110

110 = x

Hope this helped.

What is one example of an odd trigonometric function? Explain.
Soloha48 [4]

Answer:

sin(-x)

Step-by-step explanation:

Odd functions follow the relation of

f(-x)=-f(x)

Lets check for the most trivial value, does

sin(-0) = -sin(0)

Well these values both equal 0, so this is correct!

What about another value?

sin(- \frac{\pi}{2})=-1\\-sin(\frac{\pi}{2})=-1

In-fact this is strictly defined for all values of sin. Meaning that this is an odd function.
