Ф is the angle of elevation to the topo of the building from G.
length of leg adyacent to angle Ф=40m
length of leg opposite to angle Ф=15 m
tan Ф=leg opposite / leg adyacent=15/40=0.375
Ф=arctan 0.375=20.56º
The angle of elevation to the top of the building from G is 20.56º.
Answer:
x = 23
y = 10
Step-by-step explanation:
Let the two numbers be x and y where x>y
x + y = 33
<u>x - y = 13</u> Add
2x = 46 Divide by 2
2x/2=46/2 Do the division
x = 23
=============
Solve for y
x + y = 33 Substitute for x
23 + y = 33 Subtract 23 from both sides.
23-23+y = 33 - 23
y = 10
