What is the height of a triangular plate if its area is 1225 square centimeters and the length of its base is 35 centimeters, and how can you calculate this height using the formula for the area of a triangle?
Answers
Answer:
height = 70 cm
Step-by-step explanation:
the area (A) of a triangle is calculated as
A = bh ( b is the base and h the height )
given b = 35 and A = 1225 , then
1225 = × 35 × h
1225 = 17.5h ( divide both sides by 17.5 )
=
h , that is
70 = h
then the height of the triangle is 70 cm

Answer: There are 11 fish she have.
Step-by-step explanation:
Since we have given that
Number of birds = 2
Number of hamsters = 5
Let the number of fish be 'x'.
According to question, she has 6 fewer hamsters than fish.
So, our equation becomes
Hence, there are 11 fish she have.
which means 5+6=11 so there are 11 fish.
The answer is 11

Answer:
Use trigonometric ratio
Step-by-step explanation:
Since it is one side and angle of the triangle that is given, it is assumed that the triangle is a right-angled triangle
To solve for one of the two unknown lengths, use trigonometric ratio
There are 3 basic trigonometric ratio namely Sine (sin), Cosine (cos) and Tangent (tan)
Sine of the angle given = opposite side ÷ hypotenuse side
Cosine of the angle given = adjacent side ÷ hypotenuse side
Tangent of the angle given = opposite side ÷ adjacent side
Assuming the length given is the hypotenuse side and the angle is inclined to the horizontal
To find the opposite side of the triangle, multiply the hypotenuse side by the sine of the angle given

Answer:
250 litters
Step-by-step explanation:
To solve this question, we first need to know the conversion from cubic meter to liter.
1 cubic meter is equal to 1000 liters.
So, if we have 1/4 cubic meter, we can use a rule of three to find how many liters we will need:
1 m3 -> 1000 L
1/4 m3 -> x L
x * 1 = (1/4) * 1000
x = 1000 / 4 = 250 L
So we need 250 liters of water.
