Answer:
<em>900° </em>
Step-by-step explanation:
The interior angles sum = 180° ( n - 2 )
~~~~~~~~
n = 7
180° ( 7 - 2 ) = <em>900°</em>
I think it would be 6.048
Answer:
61.15 m
Step-by-step explanation:
From trigonometry :
Tan x = opposite / Adjacent
x = 28°
Tan 28 = distance from base to fire / height
0.5317094 = distance from base to fire / 115
distance from base to fire = 115 * 0.5317094
distance from base to fire = 61.15 m
Answer:
(1, 3 )
Step-by-step explanation:
Given the 2 equations
y = 3x → (1)
x + y = 4 → (2)
Substitute y = 3x into (2)
x + 3x = 4, that is
4x = 4 ( divide both sides by 4 )
x = 1
Substitute x = 1 into (1) for corresponding value of y
y = 3 × 1 = 3
Solution is (1, 3 )
