Answer: 108^{\circ}

Step-by-step explanation:

The sum of all the angles in a regular polygon with sides n , is given by :-

S_n=180^{\circ}(n-2)

Now, the sum of all the angles in a regular pentagon with 5 sides will be :-

S_5=180^{\circ}(5-2)=180^{\circ}(3)=540^{\circ}

We know that all the interior angles of a regular polygon are equal .

Therefore, the measure of each interior angle in a pentagon is given by :-

x=\dfrac{540^{\circ}}{5}=108^{\circ}

Hence, the measure of each interior angle in a pentagon=108^{\circ}

Which equations are equivalent to ? 3^3√x+4 =12 Check all that apply.
eimsori [14]

Answer:

option c

x + 4 = 64

and

option e

x = 60  

Step-by-step explanation:

Given in the question an expression

3∛x+4 = 12

∛x + 4 = 12/3

∛x + 4 = 4

Take cube on both sides of the equation

∛(x + 4)³ = 4³

x + 4 = 64

x = 64 - 4

x = 60

Use the properties of vertical angles to find the value of x.
Juliette [100K]

Answer:

The value of x= 7 and that of Angle A= 157°

Step-by-step explanation:

(x+16)° = (4x-5)° [Vertically opposite angles]

3x= 21

x= 7

Now, A + (4x-5)° = 180° [Linear pair]

A + [4(7)-5] = 180°

A + 23 = 180°

A = 180° - 23

A = 157°

Hope it helps you

In the diagram ABC is congruent to DEF. aging the values of x and y
kipiarov [429]

Answer:

x = 1, y = 46

Step-by-step explanation:

Since the triangles are congruent then corresponding sides and angles are congruent, then

DE = AB , that is

3x + 6 = 9 ( subtract 6 from both sides )

3x = 3 ( divide both sides by 3 )

x = 1

and

∠ C = ∠ F

10x + y = 56 ( substitute x = 1 )

10(1) + y = 56

10 + y = 56 ( subtract 10 from both sides )

y = 46
