Answer:
The measure of Angle A is 45.5 degrees
Step-by-step explanation:
In order to find the measure of the angle A, add it to the measures of angle B and C. Since it is an isosceles triangle, we know that B and C have the same measure. Then we set this equal to 180.
A + B + C = 180
2x + 4 + 3x + 5 + 3x + 5 = 180
8x + 14 = 180
8x = 166
x = 20.75
Now we can find the measure of Angle A by putting the value of x in for x.
2x + 4 = A
2(20.75) + 4 = A
41.5 + 4 = A
45.5 = A
From the description, we have the function

Since the square root cannot be a negative number, the only thing need to do to find the domain of the function

is take the expression inside the square rot and set it greater or equal than zero:




or

We can conclude that we can use the inequality

to find the domain of

. Also, the domain of

is (∞,

]U(5,∞).
Answer:
f(g(-3)) = 5
Step-by-step explanation:
To find f(g(x)) just plug in g(x) for x in f(x)
f(x)= x - 4
f(g(x)) = (6 - x) - 4
f(g(x)) = 6 - x - 4
f(g(x)) = 2 - x
Now to find f(g(-3)) we plug in -3 for x.
f(g(-3)) = 2 - (-3)
f(g(-3)) = 2 + 3
f(g(-3)) = 5
