Sin D= opp./hyp. = 35/37
cos D= adj./hyp. = 12/37
tan D= opp./ adj. = 35/12
The two angles (6x+4) and 32 degrees are complementary angles. They add to 90 degrees. The two angles are adjacent and form a right angle. The right angle marker is the square marker. Two adjacent right angles form a straight angle (180 degrees)
Add up the angles and set the sum equal to 90. Then solve for x
(6x+4) + (32) = 90
6x+4 + 32 = 90
6x+36 = 90
6x+36-36 = 90-36 .... subtract 36 from both sides
6x = 54
6x/6 = 54/6 ... divide both sides by 6
x = 9
Since x = 9, this means that
6x+4 = 6*9+4 = 54+4 = 58
So the missing angle is 58 degrees (note how 58+32 = 90)
X is usually the representation for the unknown number.
Multiply 3 times 6 and then you get 18 all of the possible outcomes
Answer:
The length of the rectangle=16/45 feet
Step-by-step explanation:
The area of a rectangle is given by;
A=L×W
where;
A=area of the rectangle
L=length of the rectangle
W=width of the rectangle
In our case;
A=(8/10) square feet
L=unknown
W=2 1/4 feet=9/4 feet
replacing;
8/10=l×9/4
l=8/10×4/9
l=16/45 feet
The length of the rectangle=16/45 feet
