Help with finding proofs​
nadya68 [22]

Answer:

Statement: ∠XYZ = ∠ABC     Reasons: Below

Step-by-step explanation:

For two angles to be complementary means that the sum of the two angles is equivalent to 90°. When an angle has one of those little squares, that means the angle is a right angle, or a 90° angle. Also, since it's given that line segment AB and line segment BC are perpendicular, this means the two lines/line segments cross each other at a right angle, which also proves that line segment AB and BC have a 90° angle.

How do you write sentences 10+k=4K
Andrei [34K]
K added to 10 gives you 4 times the value of K.

If you wanted to solve the expression:

Subtract both sides of the expression, right hand side(10+k) and left hand side(4K), by -k as you want to get rid of the variable to get simply 10 on the LHS.
10+k -k = 4k -k

If we want to subtract k from k then we get 0, and if we want to subtract k from 4k we get 3k. For the sake of simplicity think of k as an object saying if I subtract object A from object A I get zero, and so forth.

We are left with the expression:
10 = 3k
We divide both sides by 3 as to get rid of it from the RHS.
We get a solution 10/3 = k
