Answer:
B
Step-by-step explanation:
Complete the square.
Use de Moivre's theorem to compute the square roots of the right side.
Now, taking square roots on both sides, we have
Use de Moivre's theorem again to take square roots on both sides.

Answer: 262
Step-by-step explanation:
Get down the important info first:
m=7
n=17
Now replace the variables with the numbers. Your equation should be 17+35(7). First do the multiplication, 35x7, this will give you the answer 245. Now you add 17 to 245. You final answer should be 262.
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
7.m∠1+m∠2=m∠4 Subtraction rule
