Answer:

80

Step-by-step explanation:

The three angles of a triangle add to 180 degrees.  One angle is 10, the second is a right angle( which is 90 degrees).  Let the third angle be x

10 +90 +x = 180

Combine like terms

100 +x =180

Subtract 100 from each side

100-100 +x= 180-100

x = 80

80
Because you can do 10x8 Nd tht equals 80 so the answer gon be 80
