Answer:

BOTH ARE CORRECT

Step-by-step explanation:

Given that:

Triangle ABC Is right angled ;Angle ABC

Hypotenus = 15

If legs are 9 and 12 units long ;

From Pythagoras :

9² + 12² = hypotenus²

81 + 144 = 225²

2.) if:

B = 20° ; BC = will be

Using :

Cos θ = BC / 15

Cos 20 = BC / 15

BC = Cos 20 * 15

BC = 0.939692 * 15

BC = 14.09

BC = 14.1

What’s the first two steps to solve the equation 4 (2x - 3) = 1

Paladinen [302]

Answer:

1. Dividing both sides by 4

2. Adding 3 to each side

Step-by-step explanation:

The first step you want to take is to divide both sides by 4 so that you can solve for inside the parenthesis. Next, you should add three to both sides in order to isolate the variable.

The inside ring of packing tape has a diameter of 80 mm. The tape surrounding the ring is 8 mm beyond the ring. What is the dist

Nutka1998 [239]

Answer:

301.44 mm

Step-by-step explanation:

Diameter of the inside ring of a packing tape = 80 mm

The tape surrounding the ring is 8 mm beyond the ring which means the diameter of the ring including the surrounding will be:

80 + 8 + 8 = 96 mm

and its radius will be = 96/2 = 48.

To find the distance around the outer edge of the tape, we need to calculate the circumference for the ring with the tape on it.

<em>Circumference = $2\pi r$ </em>

Circumference = 2 x 3.14 x 48 = 301.44 mm

Therefore, the distance around the outer edge of the tape is 301.44 mm.
