Answer:

20, 45

Step-by-step explanation:

A triangle has 180 degrees interior angle measure. One angle measure 115 so that means the other two angles  must add up to 65.

The remaning angles form a ratio of 4:9. This means we must split 65 into a ratio of. 4:9

A ratio partition parts of something. We can add the ratio intergers to find it full length.

4+9=13.

Divide 65/13=5.

Multiply 5x4 and 5x9 serpately.

We get 20 and 45

Leto [7]

Answer:

<em><u>The</u></em><em><u> </u></em><em><u>answer</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>k</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>44</u></em><em><u>.</u></em>

Step-by-step explanation:

1) Subtract 3 from both sides.

\frac{k}{4}  = 14 - 3

2) Simplify 14 - 3 to 11.

\frac{k}{4}  = 11

3) Multiply both sides by 4.

k = 11 \times 4

4) Simplify 11 × 4 to 44.

k = 44

<em><u>Therefor</u></em><em><u>,</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>answer</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>k</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>44</u></em><em><u>.</u></em>
