1. find the length of side "a" in the figure below. also identify the type of triangle andexplain how you arrived at the answer.

Step-by-step explanation:

Look at the picture.

We have the triangle 30° - 60° - 90°. The sides are in ratio 1 : √3 : 2.

We have:

         divide both sides by √3

It's a right triangle.

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

eve and marks ratios are equivalent
