Answer:
139.71
Step-by-step explanation:
22% of 179.11 is 39.40
179.11 - 39.40 = 139.71
Answer:
11.6 km²
Step-by-step explanation:
- Divided it into two shapes, a triangle and a rectangle. Then find the area for each. The triangle is 4 km long and 2.2 km wide. The rectangle is 1.8 km wide and 4 km long.
- Solve the area for the triangle. The equation l · w ÷ 2=A will help. So, the equation would be 4 · 2.2 ÷ 2=4.4
- Then, solve the area for the rectangle by using the equation l · w=A. 1.8 · 4=7.2
- Add them together. 4.4+7.2=11.6
- Final answer - 11.6 km²
Answer:
x = 25
Step-by-step explanation:
We know that A and M are on a line, which is 180 degrees, and the little square means 90 degrees. So, ∠RAM = 180 - 90 = 90 degrees.
∠RAM = ∠RAX + ∠XAM
90 = (2x - 10) + (-3x + 125)
Now, simply combine like terms and solve for x:
90 = 2x - 3x - 10 + 125
90 = -x + 115
x = 115 - 90 = 25
Thus, x = 25.
