Answer:
Step-by-step explanation:
The set up is a right angles triangle where;
Height of the building = 30feet (opposite)
Angle of elevation = 70 degrees
Length of the ladder (hypotenuse) = x
Using SOH trig identity;
sin theta = opp/hyp
sin 70 = 30/x
x = 30/sin 70
x = 30/0.9397
x = 31.93feet
Hence the ladder must be 31.93 feet long to reach the top of the building
Step One: Find the greatest common factor of the numerator and the denominator.
Factors of 8: 1, 2, 4, 8
Factors of 18: 1, 2, 3, 6, 9, 18
Common Factors: 1, 2
Greatest Common Factor: 2
Step Two: Divide the numerator and denominator by the GCF.
8 ÷ 2 = 4
18 ÷ 2 = 9
Step 3: Write as a fraction.
Hello!
First you have to convert them all into numbers
2 = 2
47/14 = 3.35
sqrt of 5 = 2.23
0.9 = 0.9
0 = 0
Now you list them from least to greatest
The answer is
Hope this helps!
Hey !
We have two triangle and a rectangle
Now area is
2 x 1/2 x 10 x 6 = 60cm^2 ( base is 6 cm)
Area of rectangle = 12 x 16 = 192 cm^2
Total area = 192+60 = 252cm^2
