r=0.25 miles
l=2×

×0.25
=0.5 × 3.14
=1.57
120(minutes)÷2(miles)=60(minutes per mile)
60×1.57=94.2 minutes
we have to give its answer in degrees .The answer of this question is 45 degree which is between 0 snd 360 degree. i hope u will understand
Answer:
x = 88
Step-by-step explanation:
The sum of the angles in a triangle add to 180
47+45 +x = 180
Combine like terms
92+x = 180
Subtract 92 from each side
92+x-92= 180-92
x =88
We substitute the given into the equation
given: a=-1, b=2, c=

to continue, we can either find a common denominator or change the fraction to decimal.
Fraction to Decimal:

=-2.5
Equation=-2.5-1=-3.5
OR Common Denominator:
