Answer 2

Step-by-step explanation:

given. equal sides of measure - 1m

angle between them us 45

therefore. we know that in triangle angle opposite to equal side are. equal

therefore. we consider triangle abc. and. equal sides. ab and ac hence angle. opposite to them is equal therefore

in triangle. ABC

angle A + angle B+Angle C= 180

hence hence angle B And C are equal

therefore

$2(angle \: \: \: b) + 45 = 180$

$2(angle \: \: b) = 135 \\ angle \: b \: = 67.5$

therefore. angle a =4t

angle b=67.5

angle c=67.5
