Since it is a 90° angle it is equal to the sum of 6x° and 4x°, so 6+4=10 and the answer is the second one.

Adjacent angles on a straight line sum up to 180:
90 + 6x + 4x = 180

Combine like terms:
90 + 10x = 180

Subtract 90 from both sides:
10x = 90

Divide both sides by 10:
x = 9

Answer: 9

A school, hospital, and a supermarket are located at the vertices of a right triangle formed by three highways. The school and h

Elan Coil [88]

Answer:

7.1 miles

Step-by-step explanation:

Consider right triangle HospitalSchoolSupermarket. In this triangle:

HospitalSchool = 14.7 mi;
HospitalSupermaket = 11.76 mi;
School Supermarket = 8.82 mi.

The shortest road from the main entrance of the supermarket to the highway that connects the school and hospital will be the height drawn from the point Supermarket to the hypotenuse HospitalSchool.

Let the length of this road be x mi and the distance from School to point A be y mi. Use twice the Pythagorean theorem for right triangles Supermarket SchoolA and SupermarketHospitalA:

$\left\{\begin{array}{l}x^2+y^2=8.82^2\\ \\x^2+(14.7-y)^2=11.76^2\end{array}\right.$

Subtract from the second equation the first one:

$x^2+(14.7-y)^2-x^2-y^2=11.76^2-8.82^2\\ \\14.7^2-2\cdot 14.7y+y^2-y^2=11.76^2-8.82^2\\ \\-29.4y=11.76^2-8.82^2-14.7^2\\ \\29.4y=155.5848\\ \\y\approx5.24\ mi$

Thus,

$x^2=8.82^2-5.24^2=50.3348\\ \\x\approx 7.1\ mi.$

A sphere has a radius of 2x + 5. Which polynomial in standard form best describes the total surface area of the sphere? Use the

faust18 [17]

Start with the given formula for the surface area of a sphere.

$S = 4 \pi r^2$

Now substitute 2x + 5 in for r, the radius.
Then simplify the expression and write it in standard form.

$S = 4 \pi (2x + 5)^2$

$S = 4 \pi (4x^2 + 20x + 25)$

$S = 16 \pi x^2 + 80 \pi x + 100 \pi$
