Step-by-step explanation:
Answer:
We need to sketch the problem first.
Find the size of angle R.
One member travels a distance of 12km due north. Another team member heads 50degree east of north and travels a distance of 10km.
If se substute 50° of 180 we have
180-50=130°
The distance between the two team members is the missing side.
We know two sides and included angle, so we use the cosine rule.
A2+b2+c2-2bcCosA
= 102+122-(2x10x12xcos130°)
=100+144-(-147.08)
=100+144+147.08
=391.08
A==SQRT391.08
=19.775
19.7km

Answer:
1345
Step-by-step explanation:
I think it would be:
22 + x = 118 for your equation.
And then to solve, it would be:
22 + x = 118
-22 -22
x = 96
Average length of black mamba = 96 inches
However it is late where I am so my bad if that’s not what you needed
