Answer: Last option.
Step-by-step explanation:
For this exercise it is important to remember that a Right triangle is a triangle that has an angle that measures 90 degrees.
By definition, given a Right triangle, if you draw an altitutde from the vertex of the angle that measures 90 degrees (The right angle) to the hypotenuse, the measure of that altitude is the geometric mean between the measures of the two segments of the hypotenuse.
In this case, you have the Right triangle 
given in the picture attached.
You can notice that 
goes from the vertex of right angle (
) to the hypotenuse 
. Therefore, it divides the hypotenuse into two segments. These are:
and 
Therefore, is the geometric mean of the segments and .
Answer:
16
Step-by-step explanation:
b^2
Let b= -4
(-4)^2
16
Use the formula of an area of a tringle:
We have b = 11 yd, c = 24 yd and m∠A = 67°
Answer:
it's c , x= 1.5 or -4
2x^2 + 5x - 12 = 0
First factor the left side of the equation
(2x-3)(x+4)=0
Second, set the factors equal to 0
2x-3=0 or x+4=0
+3 +3 -4 -4
2x=3 -4
divide both side by 2 and you get 3/2 which equals 1.5
x=1.5 or x= -4
Answer:
x ∈ (-oo ; - 1) ∪ (+ 2 ; +oo)
Step-by-step explanation:
x ∈ (+ 2 ; +oo)
x ∈ (-oo ; - 1)
x ∈ (-oo ; - 1) ∪ (+ 2 ; +oo)
