Answer:

The answers are given below.

Step-by-step explanation:

7. EFGH is a rectangle. Slope of HE is - \frac {3}{5}

So, the slope of EF is \frac {-1}{- \frac {3}{5}}

                                  = \frac {5}{3}

8 .PQRS is a square.

So, m∠QSR = 45°

[since the diagonals bisect the internal angles of a square]

9. m∠PTQ = 90°

[since the diagonals of a square intersect each other at right angles]

10. RT = 24 unit ,

so,

PR = (2 \times 24) unit

     = 48 unit    [since the diagonals of a square bisect each other]

So, SQ = PR = 48 unit

[since the diagonals of a square are equal]

11. Yes, a squae is a rectangle

12. Since RSTU is a rectangle,

so, ∠RUS + ∠SUT = 90°

⇒3x + 6 + 5x - 4 = 90°

⇒x = 11°

So, ∠RUS = 3x + 6 = 39°

Solve the following system of equations.express your answer as an ordered pair in the format (a,b) with no spaces between the nu
frosja888 [35]

Answer: (3,2)

Step-by-step explanation:

For this set of system of equations, let's use elimination method to find x and y. Let's eliminate y first. In order to do so, the y values have to be the same. Therefore, you multiply the top equation by 3 and the bottom equation by 4.

9x+12y=51

-16x-12y=-72

Now, we can add the 2 equations together for the y to cancel out.

-7x=-21

x=3

Since we know x, we can plug it into any of the equations to find y.

3(3)+4y=17

9+4y=17

4y=8

y=2

With out x and y value, we can put them into an ordered pair. (3,2)

Find the volume of the triangular prism
juin [17]

Answer:

Remember the formula for calculating volume is: Volume = Area by height. V = A X h.

For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.
