Answer:
3.7 feet
Step-by-step explanation:
A golden rectangle is a rectangle in which the length and the width are in the ratio 1 : 1.618
If the width of the rectangle is 6, the length = 6 / 1.618 = 3.708 ft
= 3.7 (to the nearest tenth)
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

Answer:
h = 6 cm
Step-by-step explanation:
Atriangle = b×h/2
18cm² = 6cm×h/2
36cm² = 6cm×h
h = 36cm²/6cm
h = 6 cm
Hello there!
If DEF = 18, we then use the sin method, or the law of sin.
18 divide by sin90 would be F = sin45 .
We therefore end up with 12.72 but rounded would be 12.7 as 2 is lower than 5, so, it just rounds back down to 7.
Your answer: 12.7
