Angle B measures 30 degrees.
Step-by-step explanation:
Step 1:
If two angles are complementary, the sum of the two angles will equal 90°.
So if angles A and B are complementary, the sum of the angles A and B will equal 90°.
It is given that cos A = 0.5, we can determine the value of A by taking the cos inverse of the value 0.5.
Step 2:
If cos A = 0.5, A = 
So angle A is 60°.
As A and B are complementary, angle A + angle B = 90°.
So 60° + angle B = 90°, angle B = 90° - 60° = 30°.
So angle B measures 30° while angle A measures 60°.

Hey there! I"m happy to help!
We see that 1 inch is equal to 5.6 miles for this scale factor. If we have three inches, we simply multiply 5.6 by 3 to figure out how many miles this is!
5.6(3)=16.8
Therefore, Janet's home is 16.8 miles from her office.
Have a wonderful day! :D
Answer:
The answer is the letter B.
The first column represents the x-values, and the second row represents the y-values.
For that reason, if we have:
2x - 7y = -1
x + 3y = -5
Then, the matrix will be given by:
[ 2 -7
1 3]
Then, the third colum will be the equality:
[ -1
-5]
So the correct option is the letter B.
