Answer:

A. 60°

Step-by-step explanation:

From the diagram, in triangle ABC,

AB=BC=CA=15 units.

This means triangle ABC is an equilateral triangle.

All angles in equilateral triangle are congruent. The sum of all interior angles in triangle is always 180°, so one angle of equilateral triangle is equal to 60°. Thus,

∠A=∠B=∠C=60°

Sonja [21]

The way I'm reading this, your equation would be 5+0.75x=y.
If 2, 5, 8, and 10 are units, then you would plug those in individually and solve, like this:
5+0.75(2)= 6.5
5+0.75(5)=8.75
5+0.75(8)=11
5+0.75(10)=12.5
Hope this helps!

Answer:

5/18

Step-by-step explanation:

Let the numerator be x.

1/9 < x/ 18 < 1/3
2/18 < x / 18 < 6/18
2 < x < 6
x = {3, 4, 5}

Fractions that satisfy the condition:

3/18, 4/18, 5/18

The first two can be simplified further:

3/18 = 1/6, 4/18 = 2/9

The answer is 5/18
