Answer:
1.35m
Step-by-step explanation:
A 2.7 meter ladder leans against a house forming a 30° angle with the house. Exactly how far is the base of the ladder from the house?
We solve the above question using the Trigonometric function of Sine
cos theta = Opposite/Hypotenuse
From the question
Opposite = Distance of base of the ladder from the house = x
Hypotenuse = Length of the ladder = 2.7m
Theta = 30°
Hence,
sin 30 = x/2.7 m
Cross Multiply
x = sin 30 × 2.7m
x = 1.35m
Option b is correct.
Answer:
it is c
Step-by-step explanation:
it is c because the answer of 4310÷72 is 51
Answer:
x=1 or x=−9
Step-by-step explanation:
Let's solve your equation step-by-step.
x(x+8)=9
Step 1: Simplify both sides of the equation.
x2+8x=9
Step 2: Subtract 9 from both sides.
x2+8x−9=9−9
x2+8x−9=0
Step 3: Factor left side of equation.
(x−1)(x+9)=0
Step 4: Set factors equal to 0.
x−1=0 or x+9=0
x=1 or x=−9
we will segment the sqaure in the shape into the following
full square,
0.75
0.5
0.25
full square = 68
0.75 = 18 x 0.75 = 13.5
0.5 = 5 x 0.5 = 2.5
0.25 = 17 x 0.25 = 4.25
to get the area of figure, we will add up the values that we have gotten
so,
Area of the figure = 68 + 13.5 + 2.5 + 4.25
Area of the figure = 88.25 square meter
