Answer:
Step-by-step explanation:
think its b
Answer:
3
Step-by-step explanation:
1: Turn the mixed fraction into improper.
2: Multiply 3/5 to each side
3: The you get x = 3
You need to multiply the fraction instead of division because multiplying by the reciprocal is the same as dividing the normal fraction.
Answer:
the code is 25368 also the a b c d parts where needed to cross find the numbers
Step-by-step explanation:
Step-by-step explanation:
for any matrix multiplication number of columns of first matrix should be equal to number of rows of second matrix.
For AB
A has 3 columns and B has 3 rows so it matches . Hence can be multiplied.
For BA
B has 2 columns and A has 2 rows it also matches so can be multiplied
See the figure attached to better understand the problem
we now that
in the triangle ABC
tan alfa=126/120----------> 1.05
alfa=arctan (1.05)-------> alfa=46.40°
in the triangle ADC
sin alfa=DC/120----------> DC=sin(46.40°)*120---------> DC=86.90 units
the answer is 86.9 units
