Question

#1: what is the value of V Can anyone help me with these questions?

Answer 1

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
