Classify the following triangle as acute obtuse or right 132 36 12

Hey!

Acute angles are angles that measure less than 90°. Obtuse angles are angles that measure more than 90° but less than 180°. Right angles are angles that measure exactly 90°.

132° is greater than 90°, but less than 180°. That means it's an obtuse angle.

36° is less than 90°. That means it's an acute angle.

12° is also less than 90°. That means it's also an acute angle.

Since one of the angles is obtuse, it is an obtuse triangle.

Good luck and hope this helps! :)

step-by-step explanation:

1

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
