answer is 1.566 deg
Step-by-step explanation:
The angle of elevation is given by the formula
tanθ = height/distance
tanθ = H/ 240
tanθ × 240 = H
θ =( tan∧-1) 240
= <u>1.566 deg</u>
Answer:
-1/2
Step-by-step explanation:
The easiest way to do this is with cross-multiplication.
4 gallons for 30 plants is written as 4/30
x gallons for 45 plants is written as x/45
Multiply 4 x 45 = 180
divide by 30
= 6 gallons of water
Answer: x=2
Step-by-step explanation:
subtract 10x from 6x
Add -8x to both sides of equation
Add -4x and 8x
4x-2=6
Add 2 to both sides of equation
4x =6+2
Add 6 and 2
4x=8
Divide each term by 4 and simplify
X=8/4
Divide 8 by 4
X=2
