WhWhich of these four sets of side lengths will form a right triangle? Set 1 10 cm, 26 cm, 24 cm Set 2 4 in., 2 in., 6 in. Set 3

Aloiza [94]

Answer:

All four Sets didn't work

Step-by-step explanation:

You should be doing hypothnose aka: a² + b² = c²

If they both equal that means they are a right triangle.

Set 1:

24² + 26² = 110²

576 + 676 = 10²

1252 = 12100

No

Set 2:

2² + 4² = 6²

4 + 16 = 6²

20 = 36

No

Set 3:

13² + 14² = 15²

169 + 196 = 15²

365 = 225

No

Set 4:

10² + 20² = 30²

100 + 400 = 30²

500 = 900

No

a major arranges his soliders in rows to form a perfect square 40 soliders are left out if the total no. of soliders are 6281, f

LUCKY_DIMON [66]

Answer:

79 soldiers

Step-by-step explanation:

Since 40 soldiers were not included in the square, the square consists of 6241 soldiers. 6241 represents the area of the square, and the rows (r) represents a side of the square. Since the area of a square = the length of the side squared, then $6241 = r^{2}$ .

So $r = \sqrt{6241}$

r = 79

Recall that there are 2π radians in one full rotation and 360 degrees in one full rotation.

EleoNora [17]

Answer: (i) This angle is 33.41% of the full rotation.

(ii) 120.38°

Step-by-step explanation:

GIven: Measure of full rotation = 2π radians

Measure of an angle = 2.1 radians.

The percent of this angles of a full rotation = $\dfrac{2.1}{2\pi}\times100\%$

$=\dfrac{2.1\times7}{2\times22}\times100\% \ \ \ \ [\pi =\dfrac{22}{7}]\\\\=33.41\%$

i.e. This angle is 33.41% of the full rotation.

In degrees,

$\text{ 2.1 radians}=2.1\times\dfrac{180}{\pi}\\\\=2.1\times\dfrac{180}{3.14}\approx120.38^{\circ}$

Find an equation of the line passing through the point (2, -1) and the point of intersection of the lines x + 2y = 3 and 2x - 3y

RSB [31]

Answer:

y=-1 is the equation of the line

Step-by-step explanation:

x + 2y = 3 and

solve for x and y to get intersection point

multiply first equation by -2

$-2x -4y = -6$

$2x - 3y = 13$

--------------------------------------

$-7y=7$

y=-1

$x + 2y = 3$

$x + 2(-1)= 3$

$x -2= 3$

x=5

intersection point is (5,-1)

(2, -1) and (5,-1)

$slope = \frac{y_2-y_1}{x_2-x_1} =\frac{-1+1}{5-2} =0$

Slope = 0 (horizontal line)

So equation becomes y =y1 value

y=-1 is the equation of the line
