Please help. Trig: Laws of Cosines

Mathematics
1 answer:
Goshia [24]4 years ago
6 0

Answer:

44.0 units

Step-by-step explanation:

Bigger angle: 180 - 47 = 133

diagonal² = 24² + 24² - 2(24)(24)cos(133)

diagonal² = 1,937.662110792

diagonal = 44.0188835705

Jills front door is 42”wide and 84”tall .she purchased a circular table 96 inches diameter .will the table fit in the door
kipiarov [429]

Answer:

No

Step-by-step explanation:

Use Pythagorean's Theorem a² + b² = c² to find the hypotenuse. That will tell you her door's length from one corner the opposite.

42² + 84² = c²

Now solve for c

1764 + 7056 = c²

Now add the left side together and take the square root of both sides.

c = 93.914 in

That is not enough room for a 96 in diameter table to fit through.

A triangle has three sides: a, b, and c. Side a = 72 feet, and side b = 154 feet, and side c = 170 feet. True or false: this tri
Juliette [100K]

Answer:

True

Step-by-step explanation:

If the triangle was a right angled triangle then we can prove it using the Pythagoras theorem: c² = a² + b²

c is the largest side and a and b are the two smaller sides of the triangle.

So if this is true then √72² + 154² should be 170:

170² = 72² + 154²

28900 = 5184 + 23716

28900 = 28900

So we have proved using Pythagoras theorem that the triangle is a right angled triangle.
