Answer:
I don't know what the unit of measurement is, so I'll say the distance is 21. As for the average speed, its average speed is 8 per second.
Step-by-step explanation:
Height of a trapezoid:
h = 5 · sin 80° = 5 · 0.985 = 4.924
x = 5 · cos 80° = 5 · 0.17365 = 0.868
7 - x = 7 - 0.868 = 6.132
By the Pythagorean theorem:
d² = 6.132² + 4.924²
d² = 37.6 + 24.25
d² = 61.85
d = √61.85
d = 7.86 ≈ 8
Answer: The length of a diagonal brace is 8 feet.
Answer:
Melody
Step-by-step
I guess that it is :
So, when we look at Ibuki, when multiply, ,we got
When we multiply 2x and 6x, which did Melody, we got our result.
So, we can say that Melody factored correctly..
