Answer:
68.2°
Step-by-step explanation:
AC is the longest side which means 90° is at B
SinA = BC/AC
sinA = 5/sqrt(29)
sinA = 0.9284766909
A = 68.19859051
A = 68.2°
Answer:
The measure is 6°.
Step-by-step explanation:
If an angle of 96 degrees is rotated 90 degrees clockwise then the measure of the new angle will be given by
= 96° - 90° = 6°

Answer:
y= -(1/5)x +1
Step-by-step explanation:
Find slope:
(2+1)/(-5-10) = -1/5
Plug a point and slope into equation (I used -5,2):
y-2=-1/5(x+5)
Change it to slope-intercept form:
y-2=-1/5(x+5)
y-2=-1/5x-1
y=-1/5x+1
<span>Uphill distance = 1 4/5 = 9/5 = 18/10 km
Downhill Distance = 2 7/10 = 27/10 km
Total Uphill and Downhill = 18/10 + 27/10 = 45/10 = 4.5 km
Hence total level ground = Total race km - (Uphill + Downhill)
=10 - 4.5 = 5.5 km
Hence the answer is 5.5 km.</span>
