Answer:

Step-by-step explanation:
we know that
In the right triangle of the figure
The cosine of the angle of 35 degrees is equal to divide the adjacent side to the angle of 35 degrees by the hypotenuse
so
-----> by CAH
solve for x


8*8=64 8 *4(sides) is 32 but that's an equilateral triangle
Answer:

Step-by-step explanation:
The golden ratio is a special number favored by the Greeks. Its ratio roughly equals 1.618. The ratio is formed by taking a line segment and dividing it into two parts labeled a and b. The golden ratio is formed when this proportion is true
.
When you add a and b then divide by a, it will be the same as a divided by b. This will hold true only for specific lengths of a and b. This means you must divide the line segment in such a way that a and b meet this requirement.
Example:
If the line segment is 50 cm long. Split the segment into parts a and b where a = 30.9 and b = 19.1. Substitute the values into the proportion
.


1.618 = 1.618
This is the golden ratio.
D the answer is D. I know this Bc I did that 2 weeks ago and had 2 test on this and made 100% on both test
