**Answer:**

61

**Step-by-step explanation:**

Because all triangles's angles sum is always equal to 180, we can establish the equation, (9x - 31) + (7x - 2) + (4x + 33) = 180.

Simplifying, we get;

9x - 31 + 7x - 2 + 4x + 33 = 180

20x = 180

x = 9.

So, angle DCE = 7x - 2 = 7 * 9 - 2 = 63 - 2 = 61

The relationship between the height and shadow length is a direct proportionality type of relationship. That is, the higher the height, the longer the shadow and vice versa. The ratio of height to shadow length is a constant.

Therefore, if x and y are are the length of shadow of tether ball pole and flagpole receptively,

=

=> y=

When x= 1.35 m

y=(6.8/3)*1.35 =3.06 m

When x=1.8 m

y= (6.8/3)*1.8 = 4.08 m

When x= 3.75 m

y=(6.8/3)*3.75 = 8.5 m

When x= 0.6

y= (6.8/3)*0.6 = 1.36 m

When x=2

y= (6.8/3)*2 = 4.533 m

Therefore, it is true that B and D are the true answers.

For the first one it might be 26? i’m not so sure

The answer is found by solving the unit rate and to find the unit rate we need to divide so 70/3 is 23.3333333 infinite now you can make it more simple by making it 23.34 and that means that the falcon travels 23.34 miles PER HOUR hope this helps

**Answer:**

0 works

**Step-by-step explanation:**

If we substitute n for 0 we get this: 0 x 3 = 0 x 2 which we can simplify to get 0 = 0.

(hope this helps)
