In the triangle above, which angle is smallest in measure?

a. ∠a
b. ∠b
c. ∠c
d. all three angles are congruent.

  A. ∠A

Step-by-step explanation:

The shortest side is BC. The smallest angle is opposite the shortest side, so is angle A.

∠A is the smallest in measure.

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
