Answer:
v = 15
Step-by-step explanation:
Sum of the angles inside a triangle add up to 180
angle 1 = 31
angle 2 = 4v+44
angle 3 = 180 - 9v
since 9v is the supplement to the angle inside the triangle then
some angle + 9v has to equal 180
which we can solve for the that angle to be 180 - 9v
therefore
180- 9v + 31+ 4v+ 44 = 180
Simplify it down by combining like terms
255 -5v = 180
subtract 255 to both sides
-5v = -75
divide by -5
v = 15

Answer:
A. 8/10
Step-by-step explanation:
(0.8 × 10) / (1 × 10) = 8/10 (since, multiplying 10 shifts the decimal point towards the right by one place)
Further, we can reduce fractions 8/10 by dividing the numerator and denominator by 2.
(8 ÷ 2) / (10 ÷ 2) = 4/5
Thus, 0.8 as a fraction is 8/10 or 4/5
