Answer:
6 cm and 8 cm
Step-by-step explanation:
Use Pythagorean theorem:
c² = a² + b²
10² = x² + (x+2)²
100 = x² + x² + 4x + 4
0 = 2x² + 4x − 96
0 = x² + 2x − 48
0 = (x − 6) (x + 8)
x = 6 or -8
x must be positive, so x = 6. Which means x+2 = 8.
Answer:
<h2>x = 64</h2>
Step-by-step explanation:
To find x we use tan
tan∅ = opposite / adjacent
From the question
The adjacent is x
The opposite is 30
So we have
tan 25° = 30/x
x tan 25 = 30
Divide both sides by tan 25
x = 30/tan 25
x = 64.34
x = 64 to the nearest tenth

Answer: The required equation is
Step-by-step explanation: We are given to write the following statement as an equation :
"The sum of one-third of a number, one-half of a number and twice the number is thirty-four".
Let the number be represented by x.
Then, one-third of the number is one-half of the number is and twice the number is
Therefore, as an equation, the given statement is written as:
Thus, the required equation is
