90,000

Step-by-step explanation:

10^4=10,000.

2*10,000=20,000

7*10,000=70,000

20,000+70,000=90,000

29. -340

30. 56, 57, 58

Step-by-step explanation: For 28

1. A = L*W

2. A = 240

3. 240 = 12*W

4. (240/12) = W

5. 20ft = W

Step-by-step explanation: For 29

X+y+z=32
x=z-4
y=x+1
z=x+4
x+x+1+x+4=32
3x+5=32
3x=27
x=9
y=10
z=13

Using the triangle diagram below in the rules for special right triangles, discover the four missing links and choose them from

Nady [450]

Answer:

The solution for the system of right triangles are, respectively: $a = 2\sqrt{6}$ , $b = 4\sqrt{3}$ , $c = 4\sqrt{6}$ , $d = 6\sqrt{2}$

Step-by-step explanation:

By Geometry, we get the following equivalencies:

$a = 2\sqrt{6}$ (45 - 45 - 90 Theorem)

$b = \sqrt{2}\cdot (2\sqrt{6})$ (45 - 45 - 90 Theorem)

$b = 4\sqrt{3}$

$c = \frac{2\sqrt{6}}{\frac{1}{2} }$ (30 - 60 - 90 Theorem)

$c = 4\sqrt{6}$

$d = \frac{2\sqrt{6}}{\frac{\sqrt{3}}{3} }$ (30 - 60 - 90 Theorem)

$d = 6\sqrt{2}$
