Answer:
Step-by-step explanation:
we know that
In the triangle abc
if
then
Because, the sum of the interior angles in a triangle must be equal to 180 degrees
therefore
Triangle abc is a right triangle
see the attached figure to better understand the problem
The sine of angle a is equal to divide the opposite side to angle a by the hypotenuse
so
The cosine of angle b is equal to divide the adjacent side to angle b by the hypotenuse
so
therefore
When two angles are complementary, the sine of one angle is equal to the cosine of the other angle and the cosine of one angle is equal to the sine of the other angle
so
29580 + 3440 = 33020. The is about 33,000mi. The answer is d.
For the first question: The equation would be set up as 30=1/2(12x) Then solve for x. (Or just plug that formula into Desmos)
Answer: x=5
Answer:
Graph A
Basically a graph of a function will have no turns if linear, 1 turn if quadratic, 2 turns if cubic, and 3 terms if quartic.
Graph A has a small turn on its right side.
Step-by-step explanation:
As we know that cotx= 1/tanx
cot36° = 1/tan36°
=>cot36°= 1/0.726543
=>so cot 36°= 1.376382
So correct answer is option D.
