Answer:

72°

Step-by-step explanation:

Triangles have angles that equal 180°

Knowing this we can use 180 - 38

180-38 = 142

Since both angles have the same values of 21 we know that their angles will be the same

So, 142 ÷ 2 equals 72

Answer: 71°

Step-by-step explanation:

Since the triangle is having two equal sides, it is an isosceles triangle, therefore it will also have equal angles.

Since one of the angle is X, the two angles will be 2X

2X + 38° = 180° ( sum of interior angles in a triangle)

2X = 180° - 38°

2X =142°

To get just one of the angles which the x is representing in the figure, we simple divide bothside by 2

2X/2 = 142/2

X = 71°

What is the solution to the following system of equations?
deff fn [24]

Answer:

D) x=-3, y=-7

Step-by-step explanation:

9x - 7y = 22

x + 3y= -24

9x - 7y = 22

x= -24-3y

9(-24-3y)-7y=22

x= -24-3y

-216-27y-7y=22

x= -24-3y

-34y=22+216

x= -24-3y

-34y=238

x= -24-3y

y=238/(-34)

x=-24-3y

y=-7

x=-24-3*(-7)

y=-7

x=-24+21

y=-7

x=-3

(x,y)=(-3,-7)

Given that f(x)=x3​, find
Harrizon [31]

Answer:

(f ∘ f)(–1) = –1

Step-by-step explanation:

To solve a composite function, rewrite using brackets and solve from inside to outside.

(f ∘ f)(x) is the same as:    f[f(x)]

Given that x = –1 in (f ∘ f)(–1), we are solving for:

f[f(–1)] = ?

Solve for f(–1) inside the square brackets first.

f(x) = x³

f(–1) = (–1)³    Simplify.

f(–1) = –1       Solved the inside.

Substitute f(–1) = –1 into the square brackets.

f[f(–1)] = f[–1]

Now, we can solve the outside.

Solve with the equation of the function, x³.

f[–1] = x³

f[–1] = [–1]³     Substitute x = –1.

f[–1] = (–1)³     Simplify.

f[–1] = –1        Final answer
