Equilateral = all sides are same
side length = 8 3/4 ÷ 3
= 35/4 ÷ 3
= 35/4 × 1/3
= 35/12
Y=3x
or
-6x + 2y= 0
hope this helps and maybe brainly!

The little square box in the corner between the vertical line and the horizontal one is a symbol indicating that angle is a right angle. It has a measure of 90°. The angles designated 1 and 2 together add up to that 90°. When angles sum to the value 90°, they are called "complementary" angles.
Since angles 1 and 2 also share a side and a vertex, they are also "adjacent" angles.
The appropriate choices are ...
- complementary angles
- adjacent angles
___
<h3>2.</h3>
The same lines define the sides of angles 1 and 2, and they share a vertex. However, they are not adjacent. They are ...
___
<h3>3.</h3>
The angles marked 157° and x° together add up to make a line, so they are supplementary (their total is 180°). They also share a vertex and a side, so they are adjacent. The appropriate choices are ...
- supplementary angles
- adjacent angles
___
<h3>4.</h3>
When two angles total 180°, they are <em>supplementary</em>, whether they have any common parts or not. Since 98° + 82° = 180°, ...
- The angles are supplementary
So since we know that you can read 10 words a second, you multiply 60 secs times 10 words. Thst leaves you with your answer of 600 words in one minute!
Hope this helps!
