Answer:
a. 18 b. 119°, 118°
Step-by-step explanation:
a. Given angles are vertical, so they are equal.
6a+11 = 2a+83
6a-2a = 83-11
4a = 72
a = 72/4
a = 18
b. Substituting the value of a in the given angles,
6a+11 = 6*18+11 = 108+11 = 119°
2a+83 = 2*18+83 = 36+83 = 118°
If x+1,000=4 what’s your answer
<span>Starting from the 1580, Lope de Vega, who created about 1500 plays, set the standards for playwrights; almost 500 of his plays are still in use till date. Vega </span>wrote his plays to please the audience and to satisfy public demand; his plays are described as witty, charming, action-packed, and realistic. This explains why <span>the theater was so popular in England, Spain, and the Spanish Empire between 1580 and 1640.</span>
for the value of 
we have the function f(x) = 1/(x-2) or 
as undefined or not defined .
<u>Step-by-step explanation:</u>
<u>Function undefined: </u> A function is undefined when it gives results which are not defined for example , infinity .
Here we have , Function f(x) = 1/(x-2) or . We need to find a value of for which this is not defined . Let's find out:
We can clearly see that it's a fractional function with numerator as 1 and denominator as x-2 . For a fractional function to be undefined it's denominator must be zero i.e. x-2 = 0 or 
⇒
⇒ 
⇒
Therefore, for the value of we have the function f(x) = 1/(x-2) or as undefined or not defined .
