The diagram shows a right-angled triangle.
a
12 cm
24 cm
Find the size of angle x.

Given that , Length of Base and Hypotenuse is 12 cm and 24 cm , respectively .

Need To Find : The measure of Angle x .

As We know that ,

Cos ∅ = Base / Hypotenuse

ㅤㅤ By Substituting known Values :

ㅤ⤀Cos x = 12/24

ㅤ⤀Cos x = ½

ㅤ⤀Cos 60⁰ = ½

Therefore,

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
