Answer:
42.1 degrees
Step-by-step explanation:
- since we have a opposite/hypotenuse ratio, that means we used sin x = o/h
- this means, sin x = 0.67
so, x =
(0.67) {sin inverse}
x = 42.06 degrees, i rounded it up to 42.1 but its up to you (or according to the question)
Answer:
Area of the rectangle is increasing with the rate of 84 cm/s.
Step-by-step explanation:
Let l represents the length, w represents width, t represents time ( in seconds ) and A represents the area of the triangle,
Given,


Also, l = 12 cm and w = 4 cm,
We know that,
A = l × w,
Differentiating with respect to t,


By substituting the values,



Hence, the area of the rectangle is increasing with the rate of 84 cm/s.
