On the road, a bike sign in the shape of an isosceles trapezoid is to be painted. The sign and its dimensions are shown below. W
Oksana_A [137]

Equation

A = (b1 + b2)*h /2


Givens

b1 = 5 feet

b2 = 7 feet

h = 3 feet


Sub and solve

Area = (5 + 7)*3/2

Area = 12*3/2

Area = 36/2

Area = 18 Square feet.

The diagram shows a right angle.<br> Write an equation to determine the value of x. Solve for x.
kramer

Answer:

8x + (6x + 6) = 90°

x = 6°

Step-by-step explanation:

because it is a right angle, the sum of the angles = 90°

8x + (6x + 6°) = 90°

simplify:

14x + 6° = 90°

subtract 6° from each side:

14x = 84°

divide both sides by 14:

x = 6°

What is the value of tan A?
Ronch [10]

For the given triangle, the tan of angle A equals \frac{3}{4} = 0.75.

Step-by-step explanation:

Step 1:

In the given triangle for angle A, the opposite side has a length of 6 cm, the adjacent side has a length of 8 cm while the hypotenuse of the triangle measures 10 cm. To calculate the tan of angle A we divide the opposite side's length by the adjacent side's length.

tan A = \frac{oppositeside}{adjacent side}.

Step 2:

The opposite side's length = 6 cm.

The adjacent side's length = 8 cm.

tan A = \frac{oppositeside}{adjacent side} = \frac{6}{8} = \frac{3}{4} = 0.75.
