We know that, the sum of measures of supplementary angles is 180°
So, the Correct choice is :
because, 65° + 115° = 180°
Answer: x=158
Explain: 3 triangle corners = 180
180-90-68 = 22
Flat corner = 180
=> x=180-22=158
Answer:
80.48m2
Step-by-step explanation:
I think this is right but it may be wrong.
5km = 5000 meters
450m+800m= 1250m
5000m-1250m= 3,750m
3 3/4 km
The answers are -4 and 3 :)
