Answer:
9.83cm
Step-by-step explanation:
Since we are not asked what to look for. We can find the height of the wall.
Let the height of the wall be H
Given
Length of the ladder l = 12fot
Angle of elevation = 55degrees
Required
Height of wall H
Using the SOH CAH TOA identity
SIn theta = opp/hyp
Sin 55 = H/12
H - 12sin55
H = 12(0.8192)
H = 9.83cm
Hence the height of the ladder is 9.83cm
Answer:
Bob swam 70 meters on Monday
Step-by-step explanation:
Let x = Meters swam on Monday
and y = Meters swam on Tuesday
x + y = 250
y = 250 - x
y = 3x - 30
250 - x = 3x - 30
4x = 280
x = 70
y = 180
The length of a side of a triangle must be less than the sum of the lengths of the other two sides and greater than the difference of the lengths of the other two sides.
12 in. + 14 in. = 26 in.
14 in. - 12 in. = 2 in.
The third side must measure more than 2 inches and less than 26 inches, but we are told that the 14-inch side is the longest side of the triangle, so the third side must measure less than 14 inches. The largest whole-number length less than 14 inches is 13 inches.
Answer: It measures 13 inches.
