Answer:
180°
Step-by-step explanation:
The sum of the measures of the interior angles formed by the boundary of this team pennant.
The shape of pennant is similar to triangle. It means pennant has 3 sides and 3 angle.
It would be triangle. As we know, the sum of measure of interior angles of a triangle is 180°
∠1 + ∠2 + ∠3 = 180°
Hence, The sum of measure of angles formed by boundary of pennant is 180°

It's a slope-intercept form where a slope = -1.5 and y-intercept = 3.
x - intercept: y = 0
Therefore we have the equation:
-1.5x + 3 = 0 |-3
-1.5x = -3 |:(-1.5)
x = 2
Answer: x-intercept = 2, y-intercept = 3
