6 0

Answer:

see explanation

Step-by-step explanation:

∠1 and 170° form a straight angle and are supplementary, thus

∠1 = 180° - 170° = 10°

∠1 and ∠3 are vertical angles and congruent , thus

∠3 = 10°

∠2, 15° and ∠3 form a straight angle and sum to 180°, thus

∠2 = 180° - 15° - 10° = 155°

Thus

∠1 = 10°, ∠2 = 155°, ∠3 = 10°

konstantin123 [22]

Correct answer is A.

g - geometric mean
$g= \sqrt{ab} 
\\
\\g= \sqrt{6} ,a=4,b=?
\\ \sqrt{6}= \sqrt{4b} 
\\ (\sqrt{6})^2= (\sqrt{4b} )^2
\\6=4b
\\
\\b= \frac{6}{4} = \frac{3}{2}=1.5$
