Answer:
a) d = 36 ft. ( using Pithagoras´theorem )
b) d = 36 ft ( Using ( function sin ) trigonometry
Step-by-step explanation:
a) Using Pythagoras´Theorem:
Diagonal (d) is the hypothenuse of a right triangle of side 25 feet, and according to Pythagoras´Theorem in a right triangle.
d² = a² + b²
In this particular case a = b = 25 feet then
d² = (25)² + ( 25)²
d = √ 2 * (25)²
d = √2 * 25
d = 1,414*25
d = 35,35
d = 36 ft.
b) Using trigonometry:
We know that sin 45° = cos 45° = √2 / 2
In a right triangle
sin α = opposite side / hypothenuse (d)
sin 45° = √2 / 2 = 25/ d
√2 *d = 2* 25
d = 50/√2
d = 50 / 1,414
d = 35,36
d = 36 ft
I think it’s H bc I don’t know I just think it is
Answer:
19 is 4/dc^2
21 is y+4/4
23 is x+2/x-2
Step-by-step explanation:
Answer: Between x = -2 and 0.
Explanation: Let's first look for an interval where the gradient is decreasing. That is, if we were given the function for each curvature or line, the derivative would be negative.
We see that only two places have a decreasing gradient (between 0 and -2 and 2 and 4).
Now, the question asks for a non linear line. So, we want to look for a curve instead of a line and thus, the only viable interval is between -2 and 0.
Answer:
124°+95°+124°+54°+R = 180°
R = 143°
