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:
not necessarily confident cuz simply it doesn't look same size it should be similar
Answer:
769
Step-by-step explanation:
Answer:
660 HM = 66000 M
Step-by-step explanation:
1 hectometer to meter = 100 meter
5 hectometer to meter = 500 meter
10 hectometer to meter = 1000 meter
20 hectometer to meter = 2000 meter
30 hectometer to meter = 3000 meter
40 hectometer to meter = 4000 meter
50 hectometer to meter = 5000 meter
75 hectometer to meter = 7500 meter
100 hectometer to meter = 10000 met
