Answer:
(13+x)cm
Step-by-step explanation:
Given data
Length of sides
1cm, 5cm, 7cm
Since the shape is four-sided and the fourth side is not given, let the fourth side be x
so
The perimeter of the polygon is
P= 1+5+7+x
P= 13+x
Hence the perimeter of the polygon is
P= (13+x)cm
Answer:
<h3><X = 63</h3>
Step-by-step explanation:
USing SOH CAH TOA
sin theta = opposite/hypotenuse
sin <X = WV/VX
sin <X = 8/9
<X = arcsin(8/9)
<X = arcsin(0.8889)
<X = 62.7 degrees
Hence the value of x is approximately 63degrees
Answer:
The number is 3.
Step-by-step explanation:
5x3=15+12=27
9x3=27
Hope this helps
Cross multiply (multiply 18 on both sides to get rid of the 18 in the denominator, and multiply "x" on both sides to get rid of the x in the denominator
36 = x² Square root both sides to get rid of the ², and to get "x" by itself
√36 = √x²
±6 = x Your answer is 6
You could have just done this too:
2(18) = x(x)
36 = x²
√36 = √x²
±6 = x
hay here is your answer and hope it's clear :) and if it's not clear [ download photo math] it maybe helpful for you ;)
