Line JM intersects line GK at point N.
mylen [45]

The statements that are true are angle MNL is complementary to angle KNL and angle GNM is supplementary to angle JNK. Option B and E

<h3>How to determine the statements</h3>

Ray NL creates two angles in the lower right quadrant.

The two angles created form a total of  90°, so the two angles formed are complementary. The relation is given as;

∠MNL + ∠KNL = ∠MNK = 90°

Hence ∠MNL and ∠KNL are complementary

∠GNM and ∠JNK are both right angles (and also vertical angles). They sum up to180°. They can be said to be supplementary.

∠GNM and ∠JNK are supplementary

Thus, the statements that are true are angle MNL is complementary to angle KNL and angle GNM is supplementary to angle JNK

What is the total height of all the plants?
Serhud [2]

Answer: 6 1/8

Step-by-step explanation:

1/8 x 2 = 1/8 x 2/1 = 2/8 = 1/4

1/4 x 3 = 1/4 x 3/1 = 3/4

3/8 x 4 = 3/8 x 4/1 = 12/8 = 1 4/8 = 1 1/2

1/2 x 3 = 1/2 x 3/1 = 3/2 = 1 1/2

5/8 x 1 = 5/8 x 1/1 = 5/8

3/4 x 2 = 3/4 x 2/1 = 6/4 = 1 2/4 = 1 1/2

Start with the big number first.

1 1/2 = 1 4/8

1 1/2 = 1 4/8

1 1/2 = 1 4/8

5/8 =     5/8

3/4 =     6/8

1/4 =      2/8

Add them all up.

1 4/8 + 1 4/8 = 2 8/8 = 3

3 + 1 4/8 = 4 4/8

4 4/8 + 5/8 = 4 9/8 = 5 1/8

5 1/8 + 6/8 = 5 7/8

5 7/8 + 2/8 = 5 9/8 = 6 1/8
