1 answer:
Answer:
16° F.
Step-by-step explanation:
Given:
The current temperature in Small town is 27 °F.
This is 5 degrees less than twice the temperature that it was six hours ago.
Question asked
What was the temperature in Small town six hours ago?
Solution:
Let the temperature in Small town six hours ago was
As given that the current temperature in Small town is 27 °F and this is 5 degrees less than twice the temperature of six hours ago, the equation will be:-
<u>27 °F = 5 degrees less than twice the temperature of six hours ago</u>
27 °F = °
Adding both sides by 5
Dividing both sides by 2
Thus, the temperature in Small town six hours ago was 16° F.

Answer:
w = 60
Step-by-step explanation:
the midsegment SU is half the measure of side RV , then
SU = RV , so
w - 30 = w ( multiply through by 2 to clear the fraction )
2w - 60 = w ( subtract w from both sides )
w - 60 = 0 ( add 60 to both sides )
w = 60
Let 'n' be the number of side of a regular polygon each angle are equal and sum of each angle equal to (n-2)×180. ∴For a regular pentagon have five equal side, n=5
∴ sum of each angle = (n-2)×180=3×180 = 540. and ecah angle = 540÷5=108°. Therefore ∠BCG = 108° and ∠ABC =108°
Here BE is one of the diagonal of regular pentagon ABCDE. BE divide ∠ABC in 1:2 ratio
Therefore ∠ABE : ∠CBE = 36: 72
∴ ∠GCB + ∠CBE = 108° +72°=180°
