A=63°
bekas [8.4K]

Answer:

B. 7.35 inches

Step-by-step explanation:

In the triangle:

  • A=63°
  • c = 7.75 inch
  • B = 47°

Now we know that:

\angle A+\angle B+\angle C=180^\circ$ (Sum of angles in a \triangle)\\63^\circ+47^\circ+\angle C=180^\circ\\\angle C=180^\circ-(63^\circ+47^\circ)\\\angle C=70^\circ

Using the Law of Sines

\dfrac{a}{\sin A} =\dfrac{c}{\sin C}\\\\\dfrac{a}{\sin 63^\circ} =\dfrac{7.75}{\sin 70^\circ} \\\\a=\dfrac{7.75}{\sin 70^\circ} \times \sin 63^\circ\\\\a=7.35$ inches (to the nearest hundredth of an inch)

92 - 16b = 12 help please
Reptile [31]

Answer:

b = -6.5

Step-by-step explanation:

92 - 16b = 12

now you want to get the number(s) and variables on different sides

92 - 16b - 92 = -16b

12 + 92 = 104

-16b = 104

now divide each side by -16

-16b / -16 = b

104 / -16 = -6.5

b = -6.5

An orange triangular warning sign by the side of the road has an area of 266 square inches. The base of the sign is 9 inches lon
pashok25 [27]

Answer: the base is 28 inches. The altitude is 9 inches

Step-by-step explanation:

Let h represent the altitude of the sign.

Let b represent the length if the base of the sign.

The warning sign is triangular in shape.

The formula for determining the area of a triangle is expressed as

Area = 1/2bh

The base of the sign is 9 inches longer than the altitude. This means that

b = h + 9

If the area of the sign is 266 square inches, it means that

266 = 1/2 × h(h + 9)

266 × 2 = h(h + 9)

532 = h² + 9h

h² + 9h - 532 = 0

h² + 28h - 19h - 532 = 0

h(h + 28) - 19(h + 28) = 0

h(h + 28) - 19(h + 28) = 0

(h + 28)(h - 19) = 0

h = 19 or h = - 28

Since the height cannot be negative, then h = 19

b = h + 9 = 10 + 9

b = 28
