Answer:In basic triangle trigonometry, we look at three trigonometric functions: sine, cosine and tangent (sin, cos and tan) with right triangles.
Trigonometry formulas triangles
Let us start by naming the parts of this triangle.
θ is one of the angles of the right triangle (but not the right angle!)
h is the hypotenuse - the longest side of the right triangle
o is opposite to the angle
a is adjacent to the angle
The three formulas to rememeber can be summed up in one acronym:
SOH CAH TOA
where s stands for sine, c for cosine and t for tangent.
The three formulas are written below:
Explanation:
Answer:
less
Explanation:
In case of rolling friction, the area of contact is less than in the case of sliding. Due to this, rolling friction is <u>less</u> than sliding friction.
As a body rolls upon another, it experience the resistance to motion which is known as rolling friction.
Sliding friction refers to a contact force that resists the sliding motion of two bodies.
