I can't remember if this is correct or not but I believe it would be 5 multiplied by 20 plus 6. As I said I don't Know for sure if this is correct or not. However, I hope it help
1.) Solve for length b.
The simpler method is to use the Pythagorean theorem. If 
, then this means that 
.
Plug in the values:
--> 
So this means that b is the square root of 72, which is 8.49
2.) Solve for ∠A.
Let's refer to the law of sines. If 
, then this means we can cross multiply. Since A is the value we are solving for, the equation should be written out like this:
--> 
A is 39.52°
3.) Solve for ∠B.
This is the easiest one. The sum of all three angle measures in a triangle add up to 180°. We already know that one of the angles is a right angle and the other 39.52°.
39.52 + 90 = 129.52
180 - 129.52 = 50.48
∠B is 50.48°.
Answer:
20
Step-by-step explanation:
we can set up the equation like this:
n/4 + 2 = 7
subtract 2 from both sides
n/4 = 5
multiply 4 to both sides and you get...
n = 20
Answer:
11
Step-by-step explanation:
The diagonals in a rectangle are the same length.
WY = XZ
6x -7 = 3x +2
3x -7 = 2 . . . . . . subtract 3x
3x +2 = 11 . . . . . .add 9 to match the expression for XZ
The length of each diagonal is 11 units.
_____
Note that we took a little shortcut to the solution. We don't actually need to know the value of x. We only need to know the value of one of the expressions for diagonal length. The expression containing "3x" is the most convenient to determine.
