The value of x is 15° and the type of quadrilateral is a rhombus.
<h3>
Quadrilateral</h3>
- A quadrilateral is a polygon that has four sides.
- The sum of all angles of a quadrilateral is 360°.
Here, we are given,
m∠A = (7x)◦, m∠B = (4x + 5)◦, m∠C =(6x + 15)◦, m∠D = (6x −5)◦
So, we will have
7x+4x+5+6x+15+6x-5=360°
23x+15°=360°
23x=345°
x=345°/23°
x=15°
Hence, the angles of the quadrilateral are:
m∠A = (7x)◦=105°,
m∠B = (4x + 5)◦ =65°
m∠C =105°
m∠D = (6x −5)◦ =85°
Since the diagonal bisects ∠B and ∠D, we get that the quadrilateral is a rhombus.

The answer is 0.602
Just introduce in a scientific calculator: log(256/64) and you will have the answer.
Answer:
Step-by-step explanation:
A jacket is $65.00. If it’s on sale for 40%, then you paid 60% of the price. Find 60% of $65.00:
![\$65\cdot 0.6=\$39](https://tex.z-dn.net/?f=%5C%2465%5Ccdot%200.6%3D%5C%2439)
Now, you have to pay 5% sales tax. 5% of $39 is
![\$39\cdot 0.05=\$1.95](https://tex.z-dn.net/?f=%5C%2439%5Ccdot%200.05%3D%5C%241.95)
Hence, the total cost of the jacket is
![\$39+\$1.95=\$40.95](https://tex.z-dn.net/?f=%5C%2439%2B%5C%241.95%3D%5C%2440.95)
