Answer:

Part 1: Angle = 36°

Part 2: Angle = 72°

Step-by-step explanation:

If we have an angle "x", then

Its complement is 90 - x, and

supplement is 180 - x

Let's write equations and solve.

<u>Part 1:</u>

Complement = 1.5 times angle

90 - x = 1.5x

90 = 1.5x + x

90 = 2.5 x

x = 90/2.5 = 36

<u>Part 2:</u>

Now using 2nd equation:

3 * angle = 2 * Supplement

3x = 2 (180 - x)

3x = 360 - 2x

3x + 2x = 360

5x = 360

x = 360/5 = 72

Steven is solving the equation 3(8−2x)+40=34. He begins with the following two steps.
STatiana [176]

Answer:

<h2>Add 24 and 40</h2>

Step-by-step explanation:

3(8 - 2x) + 40 = 34       <em>use the distributive property a(b + c) = ab+ ac</em>

3(8) + 3(-2x) + 40 = 34

24 - 6x + 40 = 34          <em>combine like terms</em>

-6x + (24 + 40) = 34      <em>Answer: Add 24 and 40</em>

-6x + 64 = 34            <em>subtract 64 from both sides</em>

-6x = -30          <em>divide both sides by (-6)</em>

x = 5
