Answer:

See below

Step-by-step explanation:

1 . Missing angle

Sum of interior angles in the triangle = 180°

  • 180° - (105° + 29°) = 36°

2. Angle 1

  • Angle 1 is exterior angle of the triangle
  • Angle 1 = 55° + 78° = 133°

3. Angle 2

  • Angle 2 = 180° - (55° = 78°) = 47°

4. The sum of exterior angle and adjacent interior angle equals 180°

If they are equal, then each will measure 180°/2 = 90°

So it is possible with the right triangle

Question 1:

We can use the sum of interior angles to solve.

= 180 - (105 + 29)

= 180 - 134

= 46°

Question 2 and 3:

Angle 1 and Angle 2 create a supplementary angle (180 degrees)

Angle 1 + Angle 2 = 180

180 - 78 - 55 = 47° (Angle 2)

180 - 47 = 133° (Angle 1)

Question 4:

If you add an exterior angle and adjacent interior angle, it will add up to be 180°. If we were to divide in half (180 / 2 = 90). A right angle is an angle that measures 90°. Thus, proves that we can work it out with two right triangles.

Best of Luck!

Stock worth $80 a share dropped in value by 15% on Tuesday, then increased by $7 the next Wednesday and, finally, increased by 1
Nutka1998 [239]
<h2>Steps</h2>

So here are a couple expressions when a value changes by percentage (p = percentage in decimal form and m = original value):

  • When <em>decrease</em>: (1 - p)m
  • When <em>increase</em>: (1 + p)m

So firstly, the $80 share dropped by 15%. Since this is a <em>decrease</em>, follow the appropriate expression:

15\%=0.15\\\\(1-0.15)*80\\0.85*80\\68

<em>On Tuesday, the share went from $80 to $68</em>

Next, on Wednesday the share increased by $7. With this, just add $68 and 7.

68+7=75

<em>On Wednesday, the share went from $68 to $75</em>

Lastly, on Thursday the share increased by 12%. Since this is an <em>increase</em>, follow the appropriate expression:

12\%=0.12\\\\(1+0.12)*75\\1.12*75\\84

<h2>Answer</h2>

<u>The final price of the share is $84.</u>
