Find the value of x rounded to the nearest tenth
2 answers:
Answer: The correct option is (C) 12.5 units.
Step-by-step explanation: We are given to find the value of x rounded to the nearest tenth.
From the figure, we see a right-angled triangle with one acute angle measuring 28°.
With respect to the angle with measure 28°, the length of the base is 11 units and the length of the hypotenuse is x units.
So, from trigonometric ratios, we have
Rounding to nearest tenth, we get
x = 12.5 units.
Thus, the required value of x is 12.5 units.
Option (C) is CORRECT.

The base is an equilateral triangle. The formula of the area of that triangle is:
a - length of side
a = 3". Substitute:
The lateral side is a rectangle.
The Total Area is equal the sum of two times of Base and three times of Lateral Side.
Answer:
The ratios are both identical. (4 over 5 and 4 over 5)
Step-by-step explanation:
Th picture below represent the image you are referring.
sin x = opposite / hypotenuse
opposite side = 4
hypotenuse = 5
sin x° = 4/5
cos y° = adjacent/hypotenuse
adjacent = 4
hypotenuse = 5
cos y° = 4/5
The ratios are both identical (4 over 5 and 4 over 5)
