If the two supplementary angles are two different lines, and if it's asking for the longer angle, which is 9x....
9x° = 180° ⇒ 20°
ans: 70 ...( it is by ; 180-110) because of straight angle= 180...........
A=1x3 means 1 row and 3 columns.
B=3x4 means 3 rows and 4 columns.
AB is a compatible multiplication because A has three columns and B has 3 rows.
However, BA is not a compatible multiplication because B has 4 columns while A has only 1 row.
The general trick is if you read the row/column of the two matrices as 1-3-3-4, and the two middle ones are identical, then AB would be a compatible multiplication. On the other hand, BA would read 3-4-1-3, since 4 and 1 are not identical, so it is not a valid multiplication.
Do remember 1x3 means 1 ROW and 3 COLUMNS.
Answer:
This is a no solution (if you're asking to solve this equation). It will lead to:
20 = 12
Which is NOT equal.
The answer is thus No Solution.
Step-by-step explanation:
4(x + 5) = 4(3 + x) ~ Distribute it
4x + 20 = 12 + 4x ~ Subtract the x
20 = 12 ~ Remaining
20 does NOT equal 12.
The answer is No Solution.
