Black_prince [1.1K]

Answer:

B. A pair of alternate exterior angles with measures of 130 and 50

Step-by-step explanation:

Find the solutions of x and y.
sladkih [1.3K]

Answer:

x = 15, y = 4

Step-by-step explanation:

By Basic proportionality theorem, we have:

x/ 5 = 18/6

x = (18*5)/6

x = 90/6

x = 15

Again By Basic proportionality theorem, we have:

12/y = 18/6

y = (12*6)/18

y = 72/18

y = 4

SURFACE AREAS - PYRAMIDS?
Bond [772]

The total surface area consists of the base area and the surface area (the area of all lateral faces). The base is a hexagon with side a=3 cm.

A_{hexagon}=6A_{triangle}=6\cdot \dfrac{1}{2} \cdot \dfrac{a^2\sqrt{3}}{4} =\dfrac{3}{4} \cdot 3^2\cdot \sqrt{3}=\dfrac{27\sqrt{3}}{4} sq. cm.

Each lateral face is an isosceles triangle with height h=12 cm and base a=3 cm. The area of one such lateral triangle is

A_{lateral}=\dfrac{1}{2}\cdot h\cdot a= \dfrac{1}{2}\cdot 12\cdot 3=18 sq. cm.

Then the total surface area is:

A_{total}= \dfrac{27\sqrt{3}}{4} +6\cdot 18=\dfrac{27\sqrt{3}}{4} +108=11.7+108=119.7 sq. cm.

Answer: 119.7 sq. cm.
