Right triangle, so one angle = 90 and sum of the other 2 angles = 90
so
71x - 1 + 20x = 90
91x = 91
x = 1
<A = 20(1) = 20
answer
<A = 20 degrees
Answer:
Step-by-step explanation:
<u>Circumference formula</u>
<u>Solving for radius</u>
- 64 = 2*3.14r
- r = 64/2*3.14
- r = 10.19 ft
Answer:
96 degrees
Step-by-step explanation:
you have two angles that each measure 42 degrees, giving you 84 degrees combined
there are 180 degrees in a triangle, therefore the vertex angle is equal to 180 minus 84, or 96 degrees
check:
42 + 42 + 96 = 180
180 = 180
Answer:
$13.4
Step-by-step explanation:
Given that :
Tip percentage = 20%
Amount of bill = $67.13
Rounding the bill Amount to then nearest dollar :
$67.13 = $67
Tip amount = 20% of $67
Tip amount = 0.2 * $67
Tip amount = $13.4

Jason is incorrect.
The caterpillar's rate is 2 ft/min
Step-by-step explanation:
The rate of motion is defined as the quotient between the distance covered (in our case 16 feet) divided by the time it took to cover that distance (in our case 8 minutes)
Then, the rate is:
