Remember the SI unit then you'll remember the formula. SI unit for speed is(ms-1). hence, just divide the distance with the time and you'll get the answer in(kmh-1)
Joel took OFF 5% to get 95%, or 0.95 instead of ADDING 5% to get 105%, or 1.05. 1.05(190)(0.8) = 159.60
Answer:
x=55
a=11.47
Step-by-step explanation:
To find x we add all the angles in the triangle. The three angles in a triangle add to 180 degrees
35+x+90 = 180
Combine like terms
125+x=180
Subtract 125 from each side
125-125+x=180-125
x= 55
To find a
sin 35 = opposite side/ hypotenuse
sin 35 =a/20
Multiply each side by 20
20sin35 =a
11.47152873 =a
I forgot how to do those lol
Answer:
x = 5.57
Step-by-step explanation:
c² = a² + b² − 2ab cos C
x² = 10² + 6² − 2(10)(6) cos 29°
x = 5.57
Your answer and steps are correct.
