Answer:
x ≈ 20.31
Step-by-step explanation:
By applying tangent rule in the given right triangle,
tan(55°) = 
Measure of the opposite side = 29 units
Measure of the adjacent side = x
Substitute these values in the expression,
tan(55) = 
x = 
x = 20.306
x ≈ 20.31
Answer:
<CDG and <CDB are supplementary angles.
The answer is B., based on the distributive property (multiply coeffictients, add exponents, change signs because of the negative number being multiplied)
Both problems give you a function in the second column and the x-values. To find out the values of a through f, you need to plug in those x-values into the function and simplify!
You need to know three exponent rules to simplify these expressions:
1)
The
negative exponent rule says that when a
base has a negative exponent, flip the base onto the other side of the
fraction to make it into a positive exponent. For example,
.
2)
Raising a fraction to a power is the same as separately raising the numerator and denominator to that power. For example,
.
3) The
zero exponent rule<span> says that any number
raised to zero is 1. For example,
.
</span>
Back to the Problem:
Problem 1
The x-values are in the left column. The title of the right column tells you that the function is
. The x-values are:
<span>
1) x = 0</span>Plug this into
to find letter a:
<span>
2) x = 2</span>Plug this into
to find letter b:
<span>
3) x = 4</span>Plug this into
to find letter c:
<span>
Problem 2
</span>The x-values are in the left column. The title of the right column tells you that the function is
. The x-values are:
<span>
1) x = 0</span>Plug this into
to find letter d:
<span>
2) x = 2
</span>Plug this into
to find letter e:
<span>
3) x = 4
</span>Plug this into
to find letter f:
<span>

Answers: a = 1b = </span>
<span>
c = </span>
d = 1e = 
f = 
Answer:
By sum interior angle of triangle is equal to third exterior angle hence
z = x + y
No find x and y
Sum triangle is 180 degree
