Answer:
x ≈ 8.8
Step-by-step explanation:
Using the sine ratio in the right triangle
sin20° = 
= 
= 
( multiply both sides by x )
x × sin20° = 3 ( divide both sides by sin20° )
x = 
≈ 8.8 ( to the nearest tenth )
Since 6x and 5x+15 are both 90 degree angles, they equal each other....
6x = 5x+15 (Subtract 5x from both sides to get x alone)
x=15
Answer:
ok the formula is Width= P
/2﹣l
68/2-18=16
the width is 16
Step-by-step explanation:
First, write the rate as a decimal by moving the decimal point two places to the left from the percent.
r = 5% = 0.05
C = p + rp
C = 30.99 + 0.05 * 30.99
C = 30.99 + 1.55
C = 32.54
Answer: The total cost is $32.54
