Ivanshal [37]

Answer:


Step-by-step explanation:

Statement                                                                        Reason

1.∠4 is an exterior angle of ΔABC                                  Given

2.∠3 and∠4 form a linear pair                                 Linear pair theorem

3.∠3 is supplementary to ∠4                        Property of supplementary angle

4.m∠3+m∠4=180°                                        Definition of supplementary angle

5.m∠1+m∠2+m∠3=180°                               Triangle sum theorem

6.m∠1+m∠2+m∠3=m∠3+m∠4                     From step 4 and 5

Which function has a domain of {x | x &gt; 8}?
Harlamova29_29 [7]

Answer:

\sqrt{x-8}

Step-by-step explanation:

The domain is given in the set-builder form and it is the set of all real numbers greater than 8.

i.e., the domain is (8, ∞).

Now, consider the function f(x) = \sqrt{x-8}. This function accepts all real numbers greater than 8 as input.

But, for values less than 8, the output is not real.

Hence, \sqrt{x-8} is the required function.
