Answer:

110 - 2x

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

x + 50 + 5x - 40 + 110 - 2x = 180, that is

4x + 120 = 180 ( subtract 120 from both sides )

4x = 60 ( divide both sides by 4 )

x = 15

Thus

x + 50 = 15 + 50 = 65°

5x - 40 = 5(15) - 40 = 75 - 40 = 35°

110 - 2x = 110 - 2(15) = 110 - 30 = 80°

The largest angle is (110 - 2x)° = 80°

Solve a(x - b) - 2k = l for k

tamaranim1 [39]

A(x - b) - 2k = l
ax - ab - 2k = l

Subtract ax, add ab to both sides

- 2k = l - ax + ab

Divide by - 2 to isolate variable K

k = (l - ax + ab) / - 2 or $k = \frac{l - ax + ab}{-2}$
