The first step to solving a system of equations using substitution is to substitute an equation equal to one variable in for that variable in the other equation.
2x+3(x+1.5)=12
Answer:
33.42 divided by 6?
Step-by-step explanation:
Answer:
38°
Step-by-step explanation:
Every triangle has 180°. This means that all the angles must sum 180°.
Answer:
There is one theorem in triangle which states that sum of any two sides of a triangle is greater than the third side. For example, if a,b and c are three sides of a triangle, then a+b>c, b+c>a and a+c>b.
So, we will use here same concept.
Let a=5cm, b=7cm and c=12cm
a+b = 5+7 = 12cm which is equal to c.
<em>But a+b should be greater than c.</em>
Therefore, the triangle doesn't exist.
