Step-by-step explanation:
In triangle ADE:
sum of all angles is 180.
3x-10+58+42=180
3x+90=180
3x=180-90
3x=90
x=90/3
x=30
As line DA and CB are parallel:
angle D=angle C
angle y=58
In angle BCE, sum of angles is 180.
z+58+42=180
z+100=180
z=180-100
z=80
Answer:
x+3y+z=21
Step-by-step explanation:
x+3y+z
4+3(5)+2
4+15+2
21
Hi hope I helped, ok so first 6×7=42 and its less than 53 so ur answer is 42
