Triangle ptg has side lengths of 18 27 cm and 13 cm what type of triangle is it

Mathematics

Angle PTG = arccos((18^2 + 13^2 - 27^2) / (2 x 18 x 13)) = arccos(-236 / 468) = arccos(-0.5043) = 120 degrees.

The triangle is an obtuse triangle (because one of the angles is greater than 90 degrees) and a scalene triangle (because all the sides are not equal).

Which number is not equal to one of the following expressions? 2,500 × 10 250,000 ÷ 100 2,500 ÷ 10
ololo11 [35]

Answer:

2,500 ÷ 10

Step-by-step explanation:

Let's evaluate each expression one after the other and find out what they both gives us, then we'd now pick or select the one that doesn't give the required answer.

For 2,500 × 10

2500*10 = 25000

For 250,000 ÷ 10

250000/100= 25000

For 2,500 ÷ 10

2500/10= 250

So from the look of the results,

The one that gave us the odd result is

2,500 ÷ 10, and that's our answer.

Find the area of the polygon with vertices of A(0,1), B(0,5), C(4,5), and D(6,1).
Papessa [141]

20

If you draw that out on a coordinate grid, you get a trapezoid with one base 6 units long, one base 4 units long and a height of 4. Using the formula for area of a trapezoid 

 h(b1 + b2)/2

where h is the height, 4, b1 is a base, 6, b2 is the other base, 4, we get

4(4+6)/2

which is 4(10)/2 or 40/2

which gets us the answer, 20
