I believe it is context clues. The reader typically looks for context clues to understand the reading.
Answer:
The resulting matrix will be 11 * 7
Step-by-step explanation:
Given
Matrices 11 * 6 multiplied by 6 * 7
Required
The dimension of the resulting matrix
When a matrix a * b is multiplies by a matrix b * c, the resulting matrix will be: a * c
In this case:


So, the resulting matrix will be:

Step-by-step explanation:
the formula for the area of a sector is
(x°(r^2)π)/360
with x being the angle
r bring the radius of the circle
(255(13.4)^2π)/360
399.6
Hope that helps :)
The answer is d.61. 66+7=73. 13+8=21. 52+9=61. 10+10=20
