Answer:
The LCM of 3 and 7 is 21.
Step-by-step explanation:
This is a right angle triangle problem
drawing a vertical line at from the point where the ramp touches the car park leaves a right angle triangle with the
opposite being 2m
hypothenus being 10m
adjacent unknown
we could use sine
SineO equal to opposite over hypothenus
SineO equal to 2/10
SineO equal to 0.2
O equal to Sine^1(0.2)
O equal to 11 .5
The angle between the ramp and the horizontal is 11.5 degrees
Answer:
Step-by-step explanation:
Soh-cah-toa is a great way to remember:
You just remember the first letters : sine= opposite/hypotenuse , for example.
10 * 6 = 60 by the time Zach joins so 125-60 = 65
Now 6 (lexie) +7 (zach) = 13 (together) and 65/13 = 5.
6*5 = 30 and 7*5 = 35. 35+30 = 65
Your answer is 5.
Answer:
B 32
Step-by-step explanation:
The exterior angle is the sum of the measure of the measure of the opposite interior angles.
151 = 119+b
Subtract 119 from each side.
151-119 = 119-199+b
32 = b
