I need help with this

17 degree

Step-by-step explanation:

in isosceles triangle, angles opposite to equal sides r equal

so let that equal angles be 2x, so one of them is x

therefore, by angle sum property

146 + x + x = 180

146 + 2x = 180

2x = 180 - 146

x = 34/2

x = 17degree

therefore, m angleM = 17 degree

Hope it helped u,

pls mark as the brainliest
