Answer:
1/5
Step-by-step explanation:
= 25 so x = -2 because = 25
if x = -2 then plug in: 5^1/2(-2) = 5^-1 = 1/5
supplementary angles are 180°
<1+<2=180°
given that <1=112°
112°+<2=180°
<2=180°-112°
<2=68°
Answer:
The height = 8 miles.
Step-by-step explanation:
Area of a trapezoid = h(a + b)/2 where h=the height and a and b are the 2 bases.
So we have:
21.2 = h(4 + 1.3)/2
5.3 h / 2 = 21.2
5.3h = 42.4
h = 42.4 / 5.3
h = 8.
9.75 x 7.2 = 70.2
Swimming Pool Area: 70.2
The Park Area: 70.2 x 1.5 = 105.3
Total Area of both Swimming Pool & Park area: 70.2 + 105.3 = 175.5
Final Answer: 175.5
