Answer:
28.8 units
Step-by-step explanation:
In order to further explain the description of the right angled triangle ABC above, I have attached a hand drawn diagram for easier understanding.
The length of A D is 5 units
The length of B D is 12 units.
From the above triangle ABC, to solve for BC we have the following ratios.
BD : BC = AD : BD
Hence,
BD/ BC = AD/BD
= 12/BC = 5/12
Cross Multiply
12× 12 = BC × 5
BC = 12 × 12/ 5
BC = 144/5
BC = 28.8 units
Therefore, the length of Line segment B C, rounded to the nearest tenth is 28.8 units
Answer:
2x - y = 3.
Step-by-step explanation:
0.2x = 0.1y + 0.3
Multiply through by 10:
2x = y + 3
2x - y = 3.
Answer:
16.703
Step-by-step explanation:
right angle triangle thus we use puthagoras theorem to find the unknown length.
By converse of pythagoras theorem,
c² = a² + b²
c = √a² + b²
where c is the hypothenuse, a and b can be any 2 side of the right angle triangle
so x = √c² - a² = √ 20² - 11² ≈ 16.703 (or u can use calculator to find the long string of decimals and then round off on your own)
Step-by-step explanation:
When studying sets of numbers students have certain misconception
1) the correct of writing the tabular notation form
2) the differentiation between sets ( example certain sets have zero and certain do not have a zero - example 2 all integers are rational numbers but all rational numbers are not integers)
3) types (kinds ) of sets . ( onto - into and binary relation)
4) Domain and Range of sets
