Matrix P has a dimensions of 3 X 4 and Matrix Q has the dimensions 4 X 5. Determine the dimensions of the matrix PQ if it is pos
sible. Explain why if it is not.
Group of answer choices
Matrix PQ would have the dimensions 3 X 4
Matrix PQ would have the dimensions 4 X 5
Matrix PQ would have the dimensions 3 X 5
These matrices can not be multiplied because their dimension don't align.

Answer:
x ≈ 29.4 ft
Step-by-step explanation:
The model is a right triangle.
Using the tangent ratio
tan40° = =
( multiply both sides by 35 )
35 × tan40° = x , then
x ≈ 29.4 ft ( to 1 dec. place )
