C ) 131 is the answer
in the upside-vertex (not inverted) triangle, angle to your left hand side would be equal to x (as interior alternate angles) = 68
and the angle to the right would be 180-y= 180-117 = 163 (as linear angles)
so the angle at the vertex = 180 - (68 + 163) =49 (as angles in a triangle sum upto 180)
so the angle mz = 180 - 49 = 131 degrees (as linear pair of angles or angle in a straight line)
Answer: The 12th term is 46x -25
Step-by-step explanation:
It is increasing by 4x and decreasing by 3 through each term, this represents the d. a1 has already been identified as 2x +8, so you just have to write down the formula and the solve form there by plugging in the 12 in (n-1) to find the answer.
Answer:
The integers are 2,3,4
Step-by-step explanation:
Let one integer be = 
Since, the integers are consecutive, so they will increase by one.
So, 2nd integer will be =
3rd integer will be =
It is given that the 3 integers add up to 9.
So, we have the sum equation as:

Solving for 
Combining like terms.

Subtracting both sides by 3.


Dividing both sides by 3.


∴ 1st integer = 
2nd integer = 
3rd integer = 
Hello,
The answer would be D, because each strip represent 10 small squares out of 100.
