Answer: B.x=10/3
Step-by-step explanation: x+3-4x=4x-7-4x −3x+3−3=−7−3 −3x/−3=−10/−3 x=10/3
Answer:
b
Step-by-step explanation:
Answer:
Step-by-step explanation:
one angle is 80
let other angle be 'x'
then third angle will also be equal to x. (given)
using angle sum property,
x + x + 80 = 180. (1)
2x=100
x=50. (2)
therefore all angles are 80,50,50
