Answer:
Each vertical bar | (pipe) equals a unit and each < (corner wedge or bracket) equals a tenth. The change of power of sixty (60 ^ 1 = 60, 60 ^ 2 = 3600, 30 ^ 3 = 216000, etc.) is represented by a space.
1. are angles 2, 3, and 7
2. is x=42, y=138
3. x=65, y=65
4. d=135 h=135 e=135 b=45 c=45 g=45 f=45
Answer:
The length of the rectangle will be equal to 4.5 cm
Step-by-step explanation:
in a rectangle, wide w is 2.8 cm and and length of diagonal is 5.3 cm. To find the length we will use pythagoras theorem, which is given as
+ =
where a = width w, b = length l and c = diagonal d
so we will now have + =
Then we will have
+ =
7.84 + = 28.09
= 28.09 - 7.84
= 20.25
l =
l = 4.5
Therefore, the length of the rectangle is 4.5 cm
