Answer:
a
Step-by-step explanation:
Let x = big number
Let y = small number
x + y = 66...Equation A
2y = x + 15...Equation B
We have two equations in two unknowns.
x + x + 15 = 66
2x = 66 - 15
2x = 54
x = 54/2
x = 27
Plug x = 27 into EITHER equation above to find y.
I will use Equation A.
x + y = 66
27 + y = 66
y = 66 - 27
y = 39
The two numbers are 27 and 39.
Answer:
2.5477 feet
Step-by-step explanation:
Refer the image attached to understand my solution.
BC = height of lamppost.
DE = Julia
AD = shadow of Julia
BD = 2 feet. AD = 5 feet
BA = BD + AD
= 2 + 5 = 7 feet
In ΔABC
tan 20° = 
BC = 7 * tan 20°
BC = 2.5477 feet
SO the height of lamppost = 2.5477 feet
