Answer:
Step-by-step explanation:
we can use the trigonometric function in a right triangle
cos x = adjacent side to the angle /hypothenuse
cos 36°= x/10 ; multiply both sides by 10
10 * cos 36° = x ; make sure your calculator mode is in degrees
8.1 = x
B. Is the answer to your question
Answer:
19,200 cm^2.
Step-by-step explanation:
The area = 1.2 * 1.6 = 1.92 m^2.
There are 100 cm to 1 meter, so 1 square meter = 100^2 = 10,000 cm^2.
Therefore 1.92 m^2 = 10,000 * 1.92 = 19,200 cm^2.
Answer:
6 kg
Step-by-step explanation:
Given is weight of an object directly varies with the mass of the object .
Let the constant of proportionality be k
So,
Weight = K×(mass of the object)
For an object , weight = 45 N
mass = 9 kg
So , 45 = K×9
K = 5.
Now, for the other object ,
Weight = 30 N. K = 5 (as obtained above)
So, 30 = 5×(mass of the object)
mass of the object = 6 kg.
