Answer:
A) √3
Step-by-step explanation:
The tangent of an angle can be found by dividing the leg opposite the angle over the leg adjacent to it.
So, we have to find them.
The 30-60-90 rule says that in a right triangle with the angles 30°, 60° and 90°, the sides opposite those angles will have the ratio of 1:√3:2.
That means the side adjacent to 60° is 2 units long and the one opposite is 2√3 units long.
Dividing those two gives us (2√3)/2, which can be simplified to √3.
Answer:
3
Step-by-step explanation: There are 3 terms there
I dont know how to solve it but since the answer shows as 6 and -7, if you plug it in as x values, one tiem as 6 and second time as -7 it doesnt equal 42
(5x-12)^2
Square factor of 25 is 5.
Square factor of 144 is 12.
Hope this helps. I didn't understand what to do with it.
Answer:
b = 5
Step-by-step explanation:
28.95 + 34b ≤ 200
34.05b ≤ 200 - 28.95
34.05b ≤ 171.05
b ≤ 5.023
b = 5 is the answer
check: 5 * 34.05 + 28.95 = 199.2
if b=6: 6 * 34.05 + 28.95 = 233.25
