The height of the triangle = 4cm</h2>
Step-by-step explanation:
Given, area of the triangle = 10 
Let the height of the triangle be h cm
Given, the base b is 3 cm less than twice its height.
b = 2h - 3 ... (1)
By formula, area of the triangle = 
bh .. (2)
substitute (1)in (2), we get
Area = (2h-3) h
10 = (2h-3) h
20 = 
- 20 = 0
solving the equation, we get x = 4, -2.5
The height of the triangle = 4cm
Answer:
67.5cm^2
Step-by-step explanation:
area of a triangle is 0.5xaxb
Answer:
Step-by-step explanation:
Even number on spinners are 5 out of 10 probability of it is 1/2 and probablity of coin landing on tails also 1/2
Probability of compound event is probability of first event multiplied by probability of second even
So 1/2×1/2=1/4
Second one is 9/10×1/2=9/20
Answer:
Step-by-step explanation:
9+7+2=18
But since there are only 12 people in the class, its overlapping. So 18-2(the people that have nether), is 16.
So 16-12 is 4. Therefore 4 people have both a brother and a sister.
