I assume that x = figure no.
It's better to write this as
Tiles = 10n-18
Thus 10(12) - 18
=120 - 18
= 102
THUS HE IS WRONG.
Answer:
-8
Step-by-step explanation
2 to the power of -1 = 0.5
5 to the power of -1 = 0.2
0.5/0.2 = 2.5
So,
(2.5)2 x -5/8 to the power of -1
-5/8 = -0.625
-0.625 to the power of -1 = -1.6
So,
(2.5)2 x -0.625
5 x -0.625
= -8
<u>Part a) </u>
we know that
An isosceles triangle has two base angles that are congruent
The sum of two base angles plus the vertex angle is equal to 
degrees
so
In this problem
Solve for x
therefore
<u>the answer part a) is</u>
the value of x is 
<u>Part b)</u> What is the measure of each base angle?
we know that
we have that
substitute the value of x in the equation
therefore
<u>the answer part b) is </u>
the measure of each base angle is 
Answer:
See Below
Step-by-step explanation:
angle BAK = 128
Find KAS
180 - 128 = 52
KAS = 52
find BKA and ABK
360 -128 = 232
232/2 = 116
BKA =116
ABK = 116
find AKS
180 - 116 = 64
AKS =64
Now you have KAS and AKS
add together and subtract sum from 360 to find BSK
52 + 64 = 116
360 - 116 =244
Let me know if incorrect, plz.
Hope this helps=)
The answer is B. Because there is 2 multiples on 5 in 1-12; 5 and 10 so now you have 2/12 so simplify it to the lowest possible fraction. 1/6
