The answer is 90, Because angle D is a 90 degree angle, and 180- 90=90, so the answer is 90.
Answer:
630/x+5 (remainder over divisor)
Answer:
2.meters
Step-by-step explanation:
Lenght of ladder = 4 m
θ = 30°
To obtain h;
Using Pythagoras rule :
Sinθ = opposite / hypotenus
Hypotenus = 4 ; opposite = h
Sin 30 = h / 4
0.5 = h / 4
h = 0.5 * 4
h = 2 m
Hence, distance between th efoot of ladder and the base of the wall is 2 m
Answer:
Well, I don't have further explanation to this question but I know the answer which is: The x-axis is the only line of symmetry
