PLZZZZ HELP ASAP PLZZZ

11111nata11111 [884]

Answer:

1. (5x - 2) + (2x - 2) + x = $180^{o}$

2. m<J = $113^{o}$

3. m<K = $44^{o}$

4. m<L = $23^{o}$

Step-by-step explanation:

Generally, the sum of angles in a triangle = $180^{o}$ .

So that;

m<J + m<K + m<L = $180^{o}$

(5x - 2) + (2x - 2) + x = $180^{o}$

5x + 2x + x -2 -2 = $180^{o}$

8x - 4 = $180^{o}$

8x = $180^{o}$ + 4

8x = 184

x = $\frac{184}{8}$

x = $23^{o}$

Thus,

m<J = (5x - 2)

= 5(23) - 2

= $113^{o}$

m<K = (2x -2)

= 2(23) - 2

= $44^{o}$

m<L = x

= $23^{o}$

Evaluated to square

denis-greek [22]

Step-by-step explanation:

The square root of a number is a number that you can square to get it, that is, a number that you can multiply by itself to get the number. So, 2 is a square root of 4, because 2 x 2 = 4, and 3 is a square root of 9, because 3 x 2 = 9.
