We have been given that length of PQ and QR is 25 cm and 8 cm respectively.
We can find possible side length of PR in order to form a triangle using triangle inequality theorem.
Triangle inequality theorem states that the sum of lengths of two sides of a triangle must be greater than length of third side of triangle.
The length of PR should be either less than sum of PQ and QR or greater than difference of PQ and QR.
Let us find the other possible length of PR.
Therefore, the length of PR should be either less than 33 or greater than 17 so that PQ, QR and PR can form a triangle.
That is the pH scale
pH = - log of the concentration of hydrogen ions in a solution.
Answer:
C. 12m
Explanation:
Let the length of the shorter arm = x
Since the length of the longer arm is equal to twice the length of the shorter arm;
• The length of the longer arm = 2x
• The area of triangle ABD = 18√3 m².
Given a triangle with two sides and the included angle, the area of the triangle is calculated using the formula below:
Therefore:
We solve for x.
Multiply x by 2 to get the length of the longer arm:
The length of the longer arm is 12m.
C is the correct option.
Answer:
1/6 hour = 10 minutes
1.5 hours = 90 minute
Therefore Isaac can solve 9 questions in 1.5 hours.
