Examine triangle abc.
what is the value of x?
37
48
127
138

The outside angle of B needs to equal 180 - 79 = 101 degrees.

The 3 outside angles of a triangle need to equal 360 degrees.

Set up the equation with what we know:

X + (x+5) + 101 = 360

Simplify:

2x + 106 = 360

Subtract 106 from both sides:

2x = 254

Divide both sides by 2:

x = 254 / 2

x = 127

2/5

Step-by-step explanation:

There are five numbers on the spinner, to find the possibility of not spinning a five, put the probability as the fraction 4/5 and since there are two sides to a coin and you don't want to roll a heads, it will be represented as 1/2 multiple the two fractions for your answer.

(4/5) times (1/2) equals 4/10=2/5
