Answer:
50 degrees
Step-by-step explanation:
The sum of the interior angles of a triangle is 180. We can find the missing angle of the triangle by subtracting out the two measurement of the triangle that we know from 180.
180 - 31 -19 = 130
This angle would be the alternate exterior angel to the parallel line QP. That angle is supplement to the angle that you are looking for. <QTP would be 50 (180 -130)

Answer:
x = 22
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the interior angles
6x+1 = 79+ 2x+10
Combine like terms
6x+1 = 2x+89
Subtract 2x from each side
4x+1 = 89
Subtract 1 from each side
4x = 88
Divide by 4
4x/4 = 88/4
x = 22
Answer:
= 2√6
Step-by-step explanation:
a² + b² = c²
1 + b² = 25
b² = 24
b = ±√24
b = ±2√6
We can forget about the minus answer because you cannot have a negative length. That does not make sense.
