Alecsey [184]

Answer:

○ b Parallel

Step-by-step explanation:

If you take a look at each group of coefficients [2x and 5y, 4x and 10y], they have a proportional relationship, so when converting from <em>Linear Standard Form</em> to <em>Slope-Intercept</em><em> </em><em>Form</em>,<em> </em>they will always have an exact same <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] of −⅖.

∠QOB=45º

Step-by-step explanation:

we have that: point O=Incenter, sides S, Q, R they form right angles with the point O,  angle OBC = 15º and angle OCR=30º, find angle QOB

we know that the sum of all the internal angles of a triangle is 180º,  so

α =180-30-15-90=45º   and  β = 180-90-α  → β = 180-90-45 =45º,

Finally  β=∠QOB=45º
