Determine the missing interior and exterior angles of the triangle shown below.

∠c=50°, ∠1=95°, ∠2=135°, ∠3=130°

Step-by-step explanation:

Let's start with . We know that, universally, every angle in a triangle will add up to be 180°. Therefore, we do . Then, This means ∠ = 50°.

Then, for the other angles, we can use the rule that a straight line is equal to 180°. So for example, ∠1 + 85° = 180.

As a result:

∠1 = °

∠2 = °

∠3 = °

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21
