Hey can you please help me posted picture of question
Olenka [21]
Hello!

The variable "n" represents an exponent.

An exponent is used to multiply a number (b) by itself "n" times. For example, if the expression were to read (b²) it would represent the following:

b × b

The same could be said for (b³):

b × b × b

Even (b^{10}):

b × b × b × b × b × b × b × b × b × b

I hope this helps!

In AJKL, JL is extended through point L to point M, m m
arlik [135]

Answer:

x = 15

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ KLM is an external angle of the triangle, thus

∠ KLM = ∠ JKL + ∠ KJL , substitute values

5x - 7 = x + 20 + 2x + 3

5x - 7 = 3x + 23 ( subtract 3x from both sides )

2x - 7 = 23 ( add 7 to both sides )

2x = 30 ( divide both sides by 2 )

x = 15
