Answer:
All points between z = 0 and z = 7 along the z-azis in R3 x-y-z plane
Step-by-step explanation:
The inequality 1 z
7 represents all sets of points on the z-axis in the R3 plane that lies bewteen z = 0 and z= 7.
It is represents a line segment joining two point z= 0 and z=7 along z- axis in the R3 plane, while x=0 and y=0 on the x-y plane.
Answer:
43.3 square inches
Step-by-step explanation:
Given two sides <em>a</em> and <em>b</em> and the angle α between them, the area of the triangle can be computed as ...
A = (1/2)ab·sin(α)
Putting the given values into the formula gives ...
A = (1/2)(14.1 in)(7.8 in)sin(52°) ≈ 43.3 in²
The area of the triangle is about 43.3 square inches.
Correct answer is: distance from D to AB is 6cm
Solution:-
Let us assume E is the altitude drawn from D to AB.
Given that m∠ACB=120° and ABC is isosceles which means
m∠ABC=m∠BAC =
And AC= BC
Let AC=BC=x
Then from ΔACD , cos(∠ACD) =
Since DCB is a straight line m∠ACD+m∠ACB =180
m∠ACD = 180-m∠ACB = 60
Hence
Now let us consider ΔBDE, sin(∠DBE) =
