The first part is addition.
45+m
If she spend a third of it, you could multiply by 1/3 or divide by 3.
Multiply: 45+m x 1/3
Divide: 45+m/3
Answer:
An impossible one...
Step-by-step explanation:
The 3 interior angles of a triangle must add up to 180°
therefore no triangle can be 25,15,20 since that would add up to 60°
Answer:
the symbol "II" means that AC and DE are parallel.
The length of AC is 12.
Step-by-step explanation:
Answer:
Slope: 6
Y-intercept: 0
Proportional
Step-by-step explanation:
The equation for this table is y = 6x + 0 or just y = 6x.
y = 6x + 0
y-value slope (x-value) y-intercept
Proportional because it crosses (0,0) on the graph.
Answer:
59.04°
58.31 inches
Step-by-step explanation:
The solution triangle is attached below :
Since we have a right angled triangle, we can apply trigonometry to obtain the angle ladder makes with the ground;
Let the angle = θ
Tanθ = opposite / Adjacent
Tanθ = 50/30
θ = tan^-1(50/30)
θ = 59.036°
θ = 59.04°
The length of ladder can be obtained using Pythagoras :
Length of ladder is the hypotenus :
Hence,
Hypotenus = √(adjacent² + opposite²)
Hypotenus = √(50² + 30²)
Hypotenus = √(2500 + 900)
Hypotenus = 58.309
Length of ladder = 58.31 inches
