Scalene triangle
Step-by-step explanation:
scalene triangle is a triangle where the lengths of all three sides are different, it comprises of both obtuse and acute angles,all giving a sum of 180 degrees
Answer:
40°
Step-by-step explanation:
e = 20°
d = 20°
c = 140°
b = 40°
Answer:
c=231.87 m
Step-by-step explanation:
When we read this example we can see that Peter will form triangle with those sides :
a=200 m,
b=180 m
cos X=cos (180-105)=cos75
x is angle.
Now, we can use this rule :

Now, let's evaluate :
