Step-by-step explanation:
Bro this problem cannot be solved. No solutions. I need at least one more angle or the type of triangle it is. Like iscoceles or scalene, or equilateral. Pls give me that info and then I can solve it for u
Answer:
What least number should be added to 15871 to make it a perfect Square
√2 is irrational because let's suppose √2 is a rational number. Then, we write
√2=a/b where a and b are whole number, b≠0
From the equality √2=a/b, it follows that 2= a²/b²( Make all of them to the second power), or a²=2×b²
Then, a is 2 times some other whole number. In symbols, a=2k where k is this other number
If we substitute a=2k into the original equation 2=a²/b², this is what we get:
2=(2k)²/b²
2=4k²/b²
2b²=4k²
b²=2k². This means that b² is even, from which follows again that b itself is we . And that is contradiction, and thus our original assumption (that √2 is rational). Therefore, √2 can not be rational
√2=1.41421356237..
√2=1.4( rounded to the nearest tenth). Hope it help!
Answer:
19°
Step-by-step explanation:
Angle DBE + Angle CBE = 90
2x - 1 + 5x - 42 = 90
7x = 133
x = 19°

<em>Square tiles, design, width, long, area, inches

For this case we have square tiles. Then, for a certain design, 8 square tiles of width and 8 square tiles of length were placed, knowing that each square tile has an area of 1 square inch. We want to know Julia's design area.
So, if each square tile used to make the design has an area of 1 square inch, then it is 1 inch wide and 1 inch long each.
The area of a square tile is given by:
So if the and,
- If the design has 8 square tiles long, then the design length is inches
- If the design has 8 square tiles in width, then the width of the design is
Thus, the design area is given by the area of a square:
Answer:
The design area is 64 square inches
