What exactly are we solving?? the rest of the angles or the perimeter?
Answer:
The answer is 20 hours
Step-by-step explanation:
20x60=1200
1200÷60=20
5% of 20 is 1
1 Dollar added so the jeans is now 21 dollars
15 Minutes
You have 8 km in an hour.
Divide all that by two and you'll have 4 km in 30 mins.
Then divide by two again to end up with 2 km in 15 mins.
You could alternatively divide by four from the beginning, but I find this easier.
A. 3.91 m²
area of a triangle is (base x height)/2
b=3.4
h=2.3
(2.3)(3.4)=7.82
7.82/2=3.91
**the height of this triangle would be one of the sides because it is a right triangle (sides meet and form perpendicular lines, or a 90° angle)
