Answer:
10.4feet
Step-by-step explanation:
The set up wil form a right triangle
Length of the ramp is the hypotenuse
The length of the end of the ramp from the base= 10 feet (adjacent)
Angle of elevation = 15 degrees
Required
Length of the ramp
Using SOH CAH TOA
Cos theta = adj/hyp
cos 15 = 10/L
L = 10/cos15
L = 10/0.9659
L = 10.35
L ≈ 10.4 feet
Hence the length of the ramp is 10.4feet
Answer:
This is the identity property of addition which states that when you add zero to a number the results is the number itself.
Step-by-step explanation:
Hello,
Identity is a number<em> t</em> that when added to other numbers it gives the same number<em> t. </em>In mathematics, the additive identity is always 0. In this property a number is added to 0 where the sum is always the number. For example 0+ 96= 96.
Other properties in math that involve addition are the commutative property, associative property and the distributive property.
In the commutative property, when two numbers are added, the sum is the same regardless of the order of the addends. For example, 3+2=2+3
The associative property states that when three or more numbers are added, the sum is the same regardless of how the addends are grouped.For example (2+3)+4 = 2+(3+4)
The distributive property states that the sum of two numbers multiplied by a third number is equal to the sum of each addend multiplied by the third number. For example 2*(9+1)=2*9 +2*1.
