Traveled hours by a in four years = 120
<span>Traveled hours by b in four years = (120/100) * 120
</span> = 144
Excessive hours traveled by b in 4 years = 144 - 120
= 24
<span>Excessive hours traveled by b in 1.5 years = (24/4) * 1.5
</span> = 9 hours
Answer:
If the bisectors of two adjacent angles are perpendicular to each other, are the angles then supplementary angles?
Suppose two angles ABC and CBD are x and y.
x+y = 180 deg.
The bisector of angle ABC (BE) and the bisector of angle CBD (CF) will form angle EBF = (x/2)+(y/2) = 180/2 = 90 deg.
Conclusion: If the angle bisectors of two adjacent angles are perpendicular to eaxh other, the adjacent angles are supplementary angle
Adjacent angles are when the 2 angles have a common vertex and a common arm.
if the exterior sides of 2 adjacent angles are perpendicular, then the angles are complementary angles.
Then the sum of the 2 adjacent angles is a right angle - 90°.
When 2 angles add up to 90°, they are called a pair of complementary angles.
Step-by-step explanation:
Try to get the variable you are looking for by itself by either adding, subtracting, multiplying, or dividing all the things next to it and get it to the other side. once you are done substitute that into the other equations and solve. Then the answer you get you plug it in to the first simplified equation
23/14=1.6 square feet per hour
