Step-by-step explanation:
C.
its the same problem and nothing changed besides the order↑≠≈
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:
2x<14
Step-by-step explanation:
let that number be x. twice a number means, 2×that number.and now we are supposing that number is x. so 2×X =2x
and less than means <
so the expression becomes
2x<14.
