Measures of two supplementary angles are consecutive odd integers find the angles ​
torisob [31]
<h3>☀️ <u>Solution</u><u>:</u></h3>

Supplementary angles are those angles which add upto 180°. They may or may not be linear pair.

We have,

  • Two consecutive odd angles.
  • They are supplementary.

Let,

  • One of the angles be x
  • Then, other angle will be x + 2°

Then,

➝ x + x + 2° = 180°

➝ 2x + 2° = 180°

➝ 2x = 178°

➝ x = 89°

Other angle = x + 2° = 91°

Answer - 89° and 91°

⚘ Hence, solved !!

Olivia has made a pyramid model for her history project at school. The pyramid model has a square base. Each triangular side of
Tresset [83]

Answer:

278 square centimeters

Step-by-step explanation:

You need to use the Pythagorean Theorm. If you're pyramid is a perfect square, then to the middle the length is 5. Because 10/2 is 5. You then use the Pythagorean Theorm  (a^2 + b^2 =c^2) to find the side length of the traingle. When you square the hypotenuse and subtract the bottom leg sqaured, you are left with 3.46274054 after square rooting it. (c^2-a^2=b^2) Plug these into the equation for a right, rectangluar pyramid. You then get 277.9, rounded, is 278.

Hope this helps!
