Answer:
30 more bags
Step-by-step explanation:
First, find out x
x+15+2x+15=180
3x+30=180
3x=150
x=50
so the two angels are x+15=65(let's name is ∠5 for convenience), and ∠6= 2x+15=115
notice the two inner lines are marked as congruent, so
∠4=∠5=65
∠1=180-∠4-∠5=180-65-65=50
Name the right bottom angle ∠7, ∠3=∠7 and ∠3+∠7=the exterior angle 100 degree, therefore, ∠3=50
∠2+∠3=∠4, therefore, ∠2=∠4-∠3=65-50=15
∠1=50, ∠2=15, ∠3=50, ∠4=65
Answer:
20 is x ≥ 25
Step-by-step explanation:
In number 20 you put x is less than or equal to 25 ( x ≤ 25 )
It should be x is greater than or equal to 25 ( x ≥ 25 ) because it says it cannot be less than 25.
All your other answers are correct. Good job.
