Atriangle can’t be more than one right angle. true or false?

True. A triangle is not able to have more than 1 right angle.

Hope this helps.

True

Step-by-step explanation: True, triangles always have exactly 180 degrees sum of angles and 3 non-zero angles. Two right angles sum would be 180 degrees already forcing the third to be zero which is not allowed. So no triangle can have two 90 degree angles.

answer: 5100 just subtract

step-by-step explanation:

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
