Ответ:
90
Step-by-step explanation:
4x+22=-6x+192 since 4x+22 is the same as angle 5 due to parallel lines, and then 5 = -6x+192 as it is straight across.
4x+22=-6x+192
10x+22=192
10x=170
x=17
plug back in to equation
4(17)+22= 90
Ответ:
∠3 = 90°
Step-by-step explanation:
∠4 = ( 4x + 22 )° [ Vertically opposite angles ]
∠4 = ( -6x + 192)° [ Corresponding angles ]
Therefore ,
4x + 22 = - 6x + 192
4x + 6x = 192 - 22
10x = 170
x = 17
∠4 = 4x + 22 = (4 × 17 ) + 22 = 90°
∠4 = 90°
∠3 + ∠4 = 180°
∠3 + 90° = 180°
∠3 = 180° - 90°
∠3 = 90°
Ответ:
