Step-by-step explanation:

(a) a° +60°+35°=180 (sum of angles in a triangle)

a° +95° = 180

a° = 180-95 = 85°

(b) 80°+75°+ b° = ( sum of angles in a triangle )

155°+b° =180°

b= 180-155 =25°

134° + c° = 180°

c° = 180-134= 46°

(d) since this is a right angled triangle

d°+ 37° + 90° = 180°

127°+ d° = 180°

d° = 180- 127= 53°

(e) 11°+132° +e° = 180°

143° + e° = 180

e° = 180-143 = 37°

(f) this is also a right angled triangle

44° +f° +90° 180°

134° + f° = 180

f ° = 180° - 144° = 36°

An olympic hurdler accelerates at a rate of 15.5 m/s2 . what is the rate in miles/min2 ? 1. 6.89 miles/min2 2. 31.8 miles/min2 3

For this case we have to take into account the following conversions:
$1 mile = 1609.34 meters

1 minute = 60 seconds$
Let's first transform the expression to miles per seconds squared:
$(15.5) * (1 / 1609.34) = 0.009631277 mi / s ^ 2
$
Then, we transform the result to miles per minute squared.
We have then:
$(0.009631277) * (60) ^ 2 = 34.7 mi / min ^ 2
$
Answer:
the rate in miles/min^2 is:
$34.7 mi / min ^ 2$
