Step-by-step explanation:
1.Given .
2.Being vertically opposite angle.
3.Because sum of all interior angle of a triangle is always 180°.
4.From the statement of 3 number.
5.Because angle 4 = angle 3 and angle 6= angle 1 .
6.(suppose ,< is angle sign) solving this equation,
m<1 + m<2+ m<3 = m<3 + m<5 + m<1
Answer:
h(1)=-13

Step-by-step explanation:
We are given that

We have to find the recursive formula of h(n).
Substitute n=1

n=2

n=3


:
:
:

Therefore, the recursive formula is given by
h(1)=-13

Answer:
keep it a bean bro I can't even see the question
Step-by-step explanation:
Answer:

Step-by-step explanation:
For this case we know that:

And we want to find the value for
, so then we can use the following basic identity:

And if we solve for
we got:


And if we replace the value given we got:

For our case we know that the angle is on the II quadrant, and on this quadrant we know that the sine is positive but the cosine is negative so then the correct answer for this case would be:
