Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
First, let's establish that, they are co-interior angles on parallel lines. We can identify this as they form a 'C' shape on parallel lines.
Co-interior angles add up to 180°.
Therefore:
( x + 27 )° + ( 3x - 25 )° = 180°
x + 3x = 180 - 27 + 25
4x = 178
x = 178 / 4
x = 89 / 2
x = 44.5°

Answer:
C is the answer
Step-by-step explanation:
Answer:
The sine of A is equal to 4/5.
Step-by-step explanation:
The sine of an angle is defined as the length of the opposite side divided by the length of the hypotenuse.
The side opposite A is 12 units long, and the hypotenuse 15. This means that the sine of A is equal to 12/15, or 4/5.
Ok, so
Length = L
Width = L + 7
Since area = length x width, then
30 = L × (L + 7)
Remember that L + 7 Is width so...
L + 7 = 30/L
So the expression for the width in terms of length would be...
w = 30/L - 7
The answer to the question is 3 or C, 5/3
