Answer:
b. 3
Step-by-step explanation:
In a 30°-60°-90° triangle, the short side is ½ the hypotenuse [the long side is double the short side].
30°-60°-90° Triangles
x√3 → long side
x → short side
2x → hypotenuse
45°-45°-90° Triangles
x → two legs
x√2 → hypotenuse

Answer:
<em>13.1</em>
Step-by-step explanation:
A = bh
~~~~~~~
= 16 ,
= 9
A = 16 × 9 = 144
From another side area of parallelogram with hight "h" base "b"
11h = 144
<em>h</em> = 144 ÷ 11 ≈ <em>13.1</em>
To isolate x, we will first subtract 0.8 from both sides.
0.6x + 0.8 = 1.4
-0.8 -0.8
0.6x = 0.6
Now all we have to do is divide both sides by 0.6, because it is the number besides x.
0.6x/0.6 = 0.6/0.6
x = 1
So you get the answer of x = 1.
Answer:
Step-by-step explanation:
The top has area (3 cm)(5 cm), or: 15 cm^2
The bottom has the same area: 15 cm^2
Each of the ends has the area (3 cm)(2.5 cm): 7.5 cm^2
7.5 cm^2
Each of the sides has the area (2.5 cm)(5 cm) 12.5 cm^2
12.5 cm^2
-------------------
70 cm^2
The total lateral area is 70 cm^2
Answer:
77
Step-by-step explanation:
Add all the numbers together (74+88+79+70+74) then divide by the amount of numbers there are (in this case 5) So (74+88+79+70+74=385) (385/5=77)
