Answer:

A. 44º

Step-by-step explanation:

The sum of internal angles in a triangle is equal to 180 degrees, whereas the sum for a square is equal to 360 degrees. Given that three triangles depicted on figure constructs a square, it is to conclude that each is an isosceles triangle. The following relations are presented:

1) e + 92^{\circ} = 180^{\circ} Given

2) a = b, c = d Given

3) a + b + 92^{\circ} = 180^{\circ} Given.

4) c + d + e = 180^{\circ} Given.

5) b + c = 90^{\circ} Given.

6) 2\cdot a + 92^{\circ} = 180^{\circ} 2) in 3)

7) a = 44^{\circ} Algebra

8) b = 44^{\circ} By 2)

9) b= f Alternate internior angles.

10) f = 44^{\circ} By 8). Result

Hence, the answer is A.

Which of the following demonstrates the commutative property across multiplication for 2×10×7
Luba_88 [7]
Commutative property basically states that u can " commute " ...move the numbers around

so the commutative property of 2 * 10 * 7 could be 7 * 2 * 10... or 10 * 7 * 2...or 10 * 2 * 7 or 2 * 7 * 10....I think u get what I mean
