Answer:
x + 3
Step-by-step explanation:
In geometry, the definition of a triangle is a two-dimensional closed figure with three sides. Aside from this, it is proven that the sum of the angles of a triangle is 180°. This is a triangle's innate property. Therefore, any closed shape with three sides is a triangle and it follows that the sum of the three angles is equal to 180°.
It is logical therefore, that the first step in proving this is by using the definition of a triangle.
-275+X=-425
You need to find the change "X"
X=-425+275=-150

Answer:
<em>- 1.568</em>
Step-by-step explanation:
Let's assume that the base of the given logarithm is 10.
log m = 0.345 ⇒
= m
log n = 1.223 ⇒
= n
mn =
×
=
=
log
= - 1.568 × log 10 = <em>- 1.568</em>
