Answer:
14.1 =x
Step-by-step explanation:
Since this is right triangle, we can use trig functions
sin theta = opp/ hypotenuse
sin 42 = x /21
21 sin 42 = x
14.05174273 =x
Rounding to the nearest tenth
14.1 =x
Answer:
75
Step-by-step explanation:
Area of a triangle is <em>l </em>x <em>w </em>(length x width)
That's 4 cm x 12 cm. Now you could go ahead and figure it out from there, but you have to remember it wants the answer in meters. It tells us that for every 4cm, it is 5m. The easiest way to figure this out is to convert to meters before multiplying. Since 4 cm is 5m, the <em>l </em>becomes 5m. 4 goes into 12 three times. So we would do 5 x 3 to get 15m for the new <em>w. </em>Now we can solve for area.
<em>l </em>x <em>w </em>= A
5m x 15m = A
75m = A
I hope this helped :)
Answer:
dont have one
Step-by-step explanation:
The inequality is in the direction of the arrow
The arrow is like this <——— so the inequality is <
It is an open circle so that means -1 is not included
x<-1
Or choice A
Answer:
Below in bold.
Step-by-step explanation:
The volume of a cube = x^3 where x is the length of each edge.
1. Volume = (2/3)^3 = 2^3 / 3^3 = 8/27 unit^3.
2. Edge length x = ∛(27/64) = 3/4 units.
3. Side length of the square = = √(1/16) = 1/4 units.
