Look at the diagram of the scenario below. A steep downhill ski slope is
intersected at an angle by a less steep ski slope. Safety fences need to be set up
in the locations shown. The angles of the fences, angles 1 and 2, can be
determined by finding the relationship between the angles a and b.

-2 is the right

answer: 414,377,008

step-by-step explanation:

just multiply it

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
