Answer:

C. 55°

Step-by-step explanation:

Note the total measurement of angles for a triangle. The total measurement of all angles in a triangle = 180°

Note that m∠C is a right angle (as shown through the square), and that right angles = 90°

Subtract to find the measurement of the unknown angle (∠B)

∠B = 180 - (∠A + ∠C)

∠B = 180 - (35 + 90)

Simplify. Combine like terms. First, add (solve parenthesis), then subtract.

∠B = 180 - (125)

∠B = 55

m∠B = C. 55°

Perpendicular to y = 2x – 6 and passing through (4,3)

ladessa [460]

Answer:

y = - 1/2x + 5

Step-by-step explanation:

y = 2x – 6 slope = 2

Perpendicular line slope = -1/2

for (4 , 3) y = mx + b y = 3, x = 4, m = -1/2

b = y - mx = 3 - (-1/2) x 4 = 5

equation: y = - 1/2x + 5
