**Answer:**

38°

**Step-by-step explanation:**

EFGH is an isosceles trapezoid (a trapezoid with two congruent legs is isosceles)

∠HGF=70° (base angles of an isosceles trapezoid are congruent)

∠EGH=32° (angles in a triangle add to 180°)

∠FGE=38° (angle subtraction postulate)

**Answer:**

-11

**Step-by-step explanation:**

You need to find the difference in y-coordinates and divide that difference into a 7:3 ratio. Then you add that to the y-coordinate of point J.

Difference in y:

-20 - 10 = -30

7 + 3 = 10

7/10 * (-30) = -21

Add -21 to 10:

10 + (-21) = -11

The y-coordinate is -11.

**Answer: **20%

**Step-by-step explanation: **Since the number changes from 15 to 18, it's getting bigger which means it increases. To find the percent increase, we use the formula shown.

The amount of change is the difference between the two numbers. In this case, we would subtract 18 - 15 which equals 3. Then, we put 3 over our original number which is 15.

3 ÷ 15 = 0.2

Now, we need the percent increase which means we need to write 0.2 as a percent by moving the decimal point two places to the right to get 20%.

Therefore, the percent increase is 20%

**Answer:**

450,000

**Step-by-step explanation:**

899,765 to the nearest hundreds of thousands is 900,000 and the mid point of that should be 450,000 if I'm right
