Answer:
1. 5x + 5*2 = 30
2. 5x + 2 = 27
Step-by-step explanation:
Step-by-step explanation:
∠4 = ∠1 & ∠2 = ∠3
360 - 2(98) = ∠2 + ∠3
∠3 = 164/2
∠3 = 82°

Step-by-step explanation:
Answer:
Step-by-step explanation:
let each angle=A
A+A+A=180
3A=180
A=180/3=60°
as the angles are equal so sides are equal.
16+y=46
y=46-16=30
applying sine formula

z+x=60
40+x=60
x=60-40=20°
