Have a great day :)
Answer:
I believe this is pathgorean theorem, which I did at the beginning of alegbra last year. It is basically finding the missing side of a triangle. (Trust me some of the easiest stuff you do all year) Below are my notes from last year. I hope it helps! Good Luck!!!
Step-by-step explanation:
Given two sides
If you know two other sides of the right triangle, it's the easiest option; all you need to do is apply the Pythagorean theorem:
a² + b² = c²
if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root:
a = √(c² - b²)
if leg b is unknown, then
b = √(c² - a²)
for hypotenuse c missing, the formula is
c = √(a² + b²)
<span>1.7a+0.3a=4/5
2a = 4/5
a = 4/5 * 1/2
a = 4/10
a = 2/5</span>
a. my opposite sides are parallel
FALSE. Only the basis sides are parallel.
<u>b. I am a quadrilateral </u>
TRUE. A trapezium has 4 sides.
c. I have all the sides equal
FALSE. The trapezium is a special shape in that it does not, unlike the square or rectangle, have to have any equal side lengths.
