4, 4+4 is 8 which is double of 4
What is the question? i think that’s important
The total cost is $22.28, rounded to the nearest half dollar is $22.50.
Answer:
4) d = 1
5) w = 11
6) q = 120
Step-by-step explanation:
<em>4)</em> 
Adding 5 on both the sides ,


Dividing both the sides by 9 ,


<em>5)</em> 
Substracting 6 from both the sides ,


Dividing both the sides by -3 ,


<em>6)</em> 
Adding 19 on both the sides ,


Multiplying both the sides by 8 ,


Isosceles right triangles have two equal sides (a and b) that are not the hypotenuse (c). And when two sides are equal, so are their opposite angles. There are only 180° degrees in any triangles, thus the right angle = 90°, so 90 left for the two equal, means that 2x=90,
x = 45°.
There are several ways to go about solving a triangle like this. The best and easiest is simply to memorize that the hypotenuse is exactly root2 times the other sides. Or, each isosceles side is the hypotenuse (c) ÷ root2

Another way to do it is the longer proof of Pythagorean Theorem:
