Answer:
x = 25 degrees ∠HKL = 102 degrees
Step-by-step explanation:
The whole thing equals 180, since it is a straight angle
The value of HKL is 180 - 78 = 102
So that means 4x + 2 = 102
Subtract 2 from both sides:
4x = 100
Divide both sides by 4:
x = 25
The lemght could be 15 because a triangle has two long sides and one short one and the two are equivalent
Find the domain of
y = log(x + 3)
Logarithms can only be taken for positive numbers. So you must have
x + 3 > 0
x > – 3 ✔
So the domain of the function is
D = {x ∈ R: x > – 3}
or using the interval notation
D = (– 3, +∞)
I hope this helps. =)
Answer:
6 = r
Step-by-step explanation:
V = 
πr³ Use this equation to find the volume of a hemisphere
144π = πr³ Divide both sides by π
216 = r³ Take the cube root of both sides
6 = r
