A rhombus diagonals form right angles. The diagonals also cut in half the angles
use cosine: cos38 =
a = 20cos38
a=15.8
Given the graph, you can assume that f(x) is the y of an equation.
When f(2) is given, this means that what is the y value when x=2?
As you can see, the solution is between 8 and 10. Meaning that the closest answer is 9.
Hope I helped :)
First use the
Pythagorean theorem to find the hypotenuse h of the right triangle.
h = √(62 + 82)
= √(36 + 64)
= 10
Answer:
71°
Step-by-step explanation:
12/36 = 1/3
inverse cos(1/3) = 70.53 = 71
