The measure of the second angle of a triangle is twice the measure of the first. The measure of the third angle is six times the measure of the first.
What measure is the third angle?

Answers

Answer 1

Step-by-step explanation:

So,Let Angle 1 be x, Angle 2 be 2x, Angle 3 be 6x...

Now,

Angle 1 + Angle 2 + Angle 3 = 180°

( Sum of all angles of the triangle)

x + 2x +6x = 180°

x + 8x = 180°

9x = 180°

x = 180°/9

x = 20°

Therefore,

Angle 1 = x = 20°Angle 2 = 2x = 2 × x = 2×20° = 40°Angle 3 = 6x = 6 × x = 6×20° = 120°

So, 20°,40°,120° are the 3 angles of the triangle..

hope it helps!!!

A cross country race has 45 runners competing for first through fourth place. Complete the statement describing this situation. This is an example of a There are possible arrangements of first through fourth place winners. ​

Answers

"This is an example of a combination. There are 148,995 possible arrangements of first through fourth place winners. ​

If a  cross country race has 45 runners competing for first through fourth place, this statement is an example of a combination.

Combination has to do with selection. Since we are to select thee first four positions from the 45 runners. To get the possible number of arrangements, we will use the combination formula;

nCr = n!/(n-r)!r!

45C4 = 45!/(45-4)!4!

45C4 = 45!/41!4!

45C4 = 45*44*43*42*41!/41!*4!

45C4 = 45*44*43*42/4*3*2

45C4 = 3,575,880/24

45C4 = 148,995

Therefore the correct statement is that "this is an example of a combination. There are 148,995 possible arrangements of first through fourth place winners. ​

The round off value of 38.23 to the nearest whole number is?

Answers

Answer:

38

Step-by-step explanation:

38.23 is closest to 28, because neither the .2 or .03 is high enough to round the last whole number up

Answer:

Rounding 38.23 to the nearest whole number would be 38

Step-by-step explanation:

Rounding 38.23 to the nearest whole number would be 38 because the extra 0.23 is less than 0.50

If it was 0.50, the answer would go up to 39.

As we got

Δ Discriminant is 0 that means , there are two identical real roots. Henceforth, Option (D) 2 real, rational roots – is correct.

The oblique prism below has an isosceles right triangle base.

An oblique right triangular prism is shown. The triangular bases have 2 sides with a length of x. The length of they hypotenuse is unknown. The distance from the 2 triangular bases is (x + 3). The vertical height of the prism is (x + 2).

What expression represents the volume of the prism, in cubic units?

One-halfx3 + x2
One-halfx3 + Three-halves x2
x3 + x2
x3 + 3x2

Answers

The volume of the prism, in cubic units is 1/2x³ + x²

The volume of the oblique prism is given as:

V = Base area * Height

Given the following

Height = x + 2Base area = area of the triangle

Base area = 1/2 (x*x)

Base area = 1/2 x²

Get the volume of the prism;

Volume of the prism = 1/2(x²)(x+2)

Volume of the prism = 1/2(x³+2x²)

Volume of the prism = 1/2x³ + 1/2(2x²)

Volume of the prism = 1/2x³ + x²

Hence the volume of the prism, in cubic units is 1/2x³ + x²
