Answer:
x = 38, y = 4
Step-by-step explanation:
Since AB = BC then the triangle is isosceles and the base angles are congruent, that is
∠ DAB = ∠ DCB = 52°
Subtract the sum of the base angle from 180° for ∠ ABC
∠ ABC = 180° - (52 + 52)° = 180° - 104° = 76°
Note that ∠ ABD = ∠ CBD, thus
x = 76 ÷ 2 = 38
BD bisects the side AC, thus DC = AD = 4
Thus y = 4
You've already correctly labeled everything you need.
-- Ignore the lines YZ and YT .
-- That leaves you with the right triangle XYW .
-- Its legs are 8 and (12+3) = 15 .
-- XY is its hypotenuse.
I'm SURE you can finish it off from here.
Answer:
sampling error i think
Step-by-step explanation:
Well one way to think of this since the equation is going through the origin is to recognize this linear function as proportional and can be represented by y = kx.. Where 'k' represents the constant of proportionality. We can find the constant of proportionality by asking ourselves what can we multiply the x coordinate by to get the y coordinate for each point on the line? Consider the point (1, n) You can see the constant of proportionality would be 'n' and our equation would then be y = nx
