Answer:
The length of the shortest side of the triangle is 10 units.
Step-by-step explanation:
Let <em>a</em> be the shortest side of the isosceles triangle and <em>b</em> be the two congruent sides.
The congruent sides <em>b</em> are each one unit longer than the shortest side. Hence:
The perimeter of the isosceles triangle is given by:
This is equivalent to the perimeter of a square whose side lengths are two units shorter than the shortest side of the triangle. Let the side length of the square be <em>s</em>. Hence:
The perimeter of the square is:
Since the two perimeters are equivalent:
Substitute for <em>b: </em>
<em />
<em />
Solve for <em>a</em>. Distribute:
Simplify:
Hence:
The length of the shortest side of the triangle is 10 units.
Answer:
solve it yourself
Step-by-step explanation:
length of ist part= 30 cm
breadth of ist part = 21 cm
area of ist part = 630 cm
diameter of 2nd part= 21 cm
area of 2nd part = ¼dπ
π= 22/7
= ¼× 21 ×22/7
=3×10.5
= 31.5cm²
total area = ist part +2nd part + 3rd part
=
Yes, the same number can be written in word form and standard form because even though the number is in a different form, it doesn't change the number or any of it's values, as they would all be equivalent to that one number.
Answer:
The answer is 6.25
Step-by-step explanation:
Root 38 is exactly 6.161441400297. That number estimated would be 6.20 sine 6.16 is close to 6.20. The closest number to 6.20 is 6.25.
Note that 13 times 4 is 52.
Note also the log rule for multiplication: log ab=log a + log b.
Thus, log 4 + log 13 = log 52.
