Answer:
<u><em>1. the measure of the complement would be= 17</em></u>
<u><em>2. the measure of the angle is= 73</em></u>
Step-by-step explanation:
Step 1.
<em><u>Let its complementary angle be x, then the angle itself is 4x + 5.</u></em>
<em><u>As an angle plus its complement is equal to90 degrees, we have</u></em>
<em><u>x + 4x + 5 = 90</u></em>
<em><u>5x + 5 = 90</u></em>
Step 2.
<u><em>subtract 5 without the variable</em></u>
<u><em>then subtract 5 from 90</em></u>
<u><em>5x = 85</em></u>
<u><em>divide 85 by 5</em></u>
<u><em>x = 17</em></u>
<u><em>So the angle's </em></u><u><em>complement</em></u><u><em> is 17 degree.</em></u>
<u><em>the </em></u><u><em>angle</em></u><u><em> is 90 - 17 = 73 degrees.</em></u>

Area of a circle=pi x r^2= 3.14 x 8^2(half of the radius)=3.14 x 64=200.96
area of triangle= 1/2 bh=1/2(16)(8)=1/2(128)=64
200.96-64=136.96 sq.ft
First, convert 5 hours into minutes:
5 hours 60 min
------------ * --------------- = 300 min
1 1 hr
Next, find the unit rate in m/min:
9673.6 m
--------------- = 32.24 m/min
300 min
Now find the distance you can walk in 70 minutes at this rate:
32.24 m
------------- * 70 min = 2247 meters (answer)
1 min
You could walk 2247 meters (to the nearest meter) in 70 minutes.
