What is the answers for ∠A and \angle B∠B are vertical angles. If m\angle A=(7x-20)^{\circ}∠A=(7x−20) ∘
and m\angle B=(6x-1)^{\circ}∠B=(6x−1)
∘
, then find the measure of \angle A∠A.

the solution is h=10 because you add 9 to each side of the equation.

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
