The answer should be 9.

After you solve what's in the parentheses, you solve the problem starting from left to right.

6÷2(1+2)
6÷2(3)
3(3)
9

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

= $23^{o}$

A triangle can have one right angle.<br> a. True<br> b. False

iragen [17]

True because a triangle must have 3 angles that add up to 180 degrees and, since a right angle is 90 degrees, it cannot have 2 right angles
