ANSWER:
23
EXPLANATION:
all triangles have angles that have a sum of 180°
so 124+33=157
180-157=23

Step-by-step explanation:
Answer:
When you find the volume of the cylinder you square instead which isn't equal to multiplying so the answer will be more then doubled.
Step-by-step explanation:
solve by elimination
we can see that we can eliminate y from both equations by mulitpying the 2nd equation by 2 and adding them
x+6y=1
<u>4x-6y=64 +</u>
5x+0y=65
5x=65
divide both sides by 5
x=13
subsitute back
x+6y=1
13+6y=1
minus 13 both sides
6y=-12
divide by 6 both sides
y=-2
solution is x=13 and y=-2 or (13,-2) is the solution
Since, Ladder makes an angle 60

with the floor as shown in figure.
∴ ladder makes 120

angle with the positive direction of x-axis.
⇒ slope of ladder =tan120
