I feel like the answer Would be C but I could be wronge
Step-by-step explanation:
As we can see it a right angled triangle
so <y =90°
Now
3x + 11° + 25° + 90° = 180°{being sum of angles of triangle}
3x + 126° = 180°
3x = 54°
X = 18°
Answer:
x=4.2
Step-by-step explanation:
7.8x = 32.76
/7.8 /7.8
x=4.2
Answer:y+2.9=11, 2y+1=17.2, 28.4-y=20.3
