What symbol makes the sentence true? -3½ ? -3 5/9
a) ≥

b) ≤

c) <

d) >

D

Step-by-step explanation:

Both numbers are negative.  The larger the amplitude of a negative number, the smaller the number is.  Thus, -3 5/9 is smaller than -3 1/2.  Answer D is correct.

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.

there are no multiple choices
