What are the angle measures of triangle ABC? m∠A = 30°, m∠B = 60°, m∠C = 90°
m∠A = 90°, m∠B = 60°, m∠C = 30°
m∠A = 60°, m∠B = 90°, m∠C = 30°
m∠A = 90°, m∠B = 30°, m∠C = 60°

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

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
