Answer:

Step-by-step explanation:
-0.4(3i + 4i) - 0.3(-2i + 5j) + 0.2(-
+
j)
-1.2i - 1.6j + 0.6i - 1.5j -
i + 0.5j
Converting to fraction form;

<u>Solving the i part;</u>
= 
<u>Solving the j part;</u>
j
So -0.4a - o.3b + 0.2d =
- 
Answer:
Becky, because her reason I'm step 2 does not justify her 2ndbstatement.
Step-by-step explanation:
Two angles which add up to give 180° are said to be defined as supplementary angles.
The Definition of Supplementary Angles is the most appropriate statement to justify the second statement in the proof, as written by Angie, compared to the Angle Addition Postulate stated by Becky.
The Angle Addition Postulate does not justify why the two of angles both equal 180°. According to the Angle Anldditiin Postulate, sum of 2 angles that share the same side can does not necessarily have to be 180°. It could be less than or greater than 180°.
Therefore, Becky completed her proof incorrectly.
Answer:
50, 60, 70: More than one triangle
60, 15, 15: A unique triangle
80m, 65m, 20m: No triangle

200 euros 300 euros
--------------- = -----------------------------
270 dollars x dollars
using cross products
200 * x = 270 * 300
divide each side by 200
x = 270 * 300/200
x =405 dollars
