Answer:
Let's begin with a 30°-60°-90° triangle. A 30°-60°-90° triangle with a hypotenuse of 2 um
Step-by-step explanation:
This is a right angle triangle.
So, by Pythagoras theorem,
√(32^2+20^2) = x
or √(1024+400) = x
or √1424 = x
or <em>37.74 = x</em>
Answer:
A. csc θ=1/sinθ
Step-by-step explanation:
From SOHCAHTOA,
sine = opposite/ hypotenuse
Cos = adjacent / hypotenuse
Tan = opposite / adjacent
In a right angled triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the side opposite the angle. This is the inverse of sine , therefore:
Csc Ф = 1/ sinФ
Answer:
x = 5
Step-by-step explanation:
Just use the Pythagorean Triangle:
13^2 - 12^2 = x^2
x^2 = 25
x = 5
