Answer:
The last three,
2 cm, 5 cm, 6 cm
4 cm, 8 cm, 11 cm
10 in, 5 in, 13 in
As long as any two sides added together are long than the third side, it works as a triangle!
K, so since directix is below focus, it opens up (2<4)
and directix is y=something so equation is (x-h)^2+4p(y-k) where (h,k) is vertex and p is distance from focus to vertex. if it opens down, p<0, if it opens up, p>0
and the vertex is in the middle of the focus and directix
so
distance bewten (-2,4) and y=2 is 2 units
2/2=1, so 1 unit down from focus
vertex is in the middle so it is at (-2,3)
also, opens up so p=1
vertex (-2,3)
p=1
(x-(-2))^2=4(1)(y-3)
(x+2)^2=4(y-3) is an equation
Answer:

Step-by-step explanation:
Given :
Area of the rectangle =
square units
Width of the rectangle=
units
Area of the rectangle= Length* Width

Multiplying
both the sides



The length of the rectangle is 2 units
<u>Given</u>:
Given that HIJ is a right triangle.
The measure of ∠J is 90°, JI = 5, IH = 13, and HJ = 12.
We need to determine the value of sine of ∠H
<u>Value of sine ∠H:</u>
The value of sine ∠H can be determined by using the trigonometric ratios.
Thus, we have;

Substituting the values, we get;

Dividing, we get;

Taking
on both sides, we have;


Rounding off to the nearest hundredth, we get;

Thus, the measure of ∠H is 22.62°
