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.

If f(x)=x²+2x then find f(2) and f(8)

kobusy [5.1K]

Answer:

f(2) = 8, f(8) = 80

Step-by-step explanation:

$f(x)=x(x+2)$

$f(2)=2(2+2)=2(4)=8\\f(8)=8(8+2)=8(10)=80$

Create a scenario that leads to an inequality of the form ax + b > c

blagie [28]

Answer:

Johnny wants to buy a game but he doesn't have enough money. He needs to have at most $60 to buy his game. He has $5 in his piggy bank and gets $11 for every hour for working. Write an inequality where x represents his hours.

11x + 5 ≤ 60

Not that good but its better than nothing.

Given that A, O & B lie on a straight line segment, evaluate acute

Luba_88 [7]

If the value of x is 10. Then the measure of angle ∠COB will be 56°.

<h3>What is an angle?</h3>

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.

Given that A, O, and B lie on a straight line segment.

Then they make a linear angle that is 180 degrees.

Then we have

∠AOC + ∠COD + ∠DOB = 180

(3x + 94) + (x + 30) + (2x - 4) = 180

6x + 120 = 180

6x = 60

x = 10

Then the measure of angle ∠COB will be

∠COB = ∠COD + ∠DOB

∠COB = (x + 30) + (2x - 4)

∠COB = (10 + 30) + (20 - 4)

∠COB = 40 + 16

∠COB = 56°
