Okay, here we have this:
Considering the provided information, we are going to identify wich equation applies, so we obtain the following:

Where x represents the uknown number. Then finally we obtain that the correct equation is the third one.
Now, let's find the missing number solving the equation:

Finally we obtain that the number is equal to 19.
Answer:
The answer is d.
Step-by-step explanation:
<em>x </em>is "a number." When a variable and a number are next to each other, they are being multiplied. So it's 7 times a number. Then you take the product of that and add 2.
So, d is the correct answer. :D

Answer: m∠CAD = 81°
Step-by-step explanation: <u>Diagonal</u> is a line that unites opposite sides.
ABCD is a prallelogram. One property of diagonal in a parallelogram is it separates the parallelogram in 2 congruent triangles.
The figure below shows ABCD with its diagonals.
Since diagonal divides a parallelogram in 2 congruent triangles, it means the internal angles are also congruent. So
m∠BAC = m∠CAD
4x + 5 = 5x - 14
x = 19
Then, m∠CAD is
m∠CAD = 5(19) - 14
m∠CAD = 81
The angle m∠CAD is 81°.
