Solve for a. 1/3(21-3a)=6-a

Mathematics
1 answer:
OverLord2011 [107]3 years ago
5 0

Answer:

no solution

Step-by-step explanation:

Given

\frac{1}{3} (21 - 3a) = 6 - a ( multiply through by 3 to clear the fraction )

21 - 3a = 18 - 3a ( subtract 21 from both sides )

- 3a = - 3 - 3a ( add 3a to both sides )

0 = - 3 ← not possible

This indicates the equation has no solution

Give the value of x .<br><br> A. 60 degrees<br> B. 180 degrees<br> C. 120 degrees<br> D. 45 degrees
Harrizon [31]

Answer:

x=120°

Step-by-step explanation:

sum of all angles in a triangle is equal to 180

let the unknown angle be

\alpha

60 + 60 +  \alpha  = 180 \\  \alpha  = 180 - 60 - 60 \\  \alpha  = 60 \\

\alpha  + x = 180 \\ x = 180 -  \alpha  \\ x = 180 - 60 \\ x = 120

the first picture shows that two sides are the same and one angle so you know it's a SAS,    the one tick mark and that the two trialge share one common side is how you know 2 sides are the same,  and the 90 °  corner symbol shows you know an angle in each , that is also the same.

the second picture shows 3 sides the same  so SSS,  the triangles share one side, and have the tick marks, showing that each of the respective sides are the same.
