Step-by-step explanation:
Remember that complementary angles <em>always </em>add up to 90°.
We know that the two complementary angles are represented by (x) and (x+14). In other words:
So, let's solve for x.
First, combine like terms:
Let's isolate the x by subtracting 14 from both sides:
The left cancels. Subtract on the right:
Divide both sides by 2:
The left side cancels. Divide on the right:
So, the value of x is 38°.
And we're done!
Answer:
1 : 200000
Step-by-step explanation:
4 cm ⇒ 8 km
4 cm ⇒ 8 × 1000m
4cm ⇒ 8000m
4 cm ⇒ 8000 × 100 cm
4 cm ⇒ 800000cm
4 : 800000
1 : 200000
Therefore,
1 : n
1 : 200000
