En un triángulo ABC, recto en B, se traza la bisectriz interior BE y luego AQ | BE . Si m<QAC = 20, calcular m<BCD a)20° b)30° c)45° d) 25° e)35°

answer: what equations are there

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

i suppose it should be (y=2x-5)
