Answer:
x=5
Step-by-step explanation:
The sides have to be equal length
3x+4 = 5x-6
Subtract 3x from each side
3x+4-3x = 5x-6-3x
4 = 2x-6
Add 6 to each side
4+6 = 2x-6+6
10 = 2x
Divide by 2
10/2 =2x/2
5 =x
Answer:
About 5.73 cm
Step-by-step explanation:
C=2πr so
36=2πr (divide by 2)
18=πr (using 3.14 as π)
18=(3.14)r (divide by 3.14)
r=5.732484076 so
R≈5.73 cm
To find the height of the lighthouse, use
to get that h = 14 (the tangent of 45 is 1). Now for the next question, you have to use the height you just solved for to find angle y. Use
and the inverse tangent button on your calculator tells us that the angle is 28.3. Now for the last question, use the supplement of 45 to get that the angle adjacent to y is 135. 180 - 135 - 28.3 = 16.7 That's your x value.
Deposit = $1900
Amount After interest = $3875.79
% interest = 4%
Interest = 1975.79
Time For Interest Period
4/100 × 1900 × t = 1975.79
76 t = 1975.79
=26 years
Answer = 26years
