Answer:
x = 6/√3 , y = 12/√3
Step-by-step explanation:
sin 60° = opposite /hypothenus
√3/2 = 6/y
cross multiply
√3y=6 x 2 = 12
y = 12/√3
Tan 60° = opposite/adjacent
tan 60° = √3
√3 = 6/x
√3x= 6
x = 6/√3
we know that
Perimeter of a triangle is equal to
P=a+b+c
where
a,b and c are the length sides of the triangle
<u>Find the perimeter of the triangles</u>
<u>Triangle N 1</u>
P=(x-2)+(x)+(3x+1)-------> P=5x-1
<u>Triangle N 2</u>
P=(2x-5)+(x+4)+(6x-7)------> P=9x-8
equate the perimeters
5x-1=9x-8--------> 9x-5x=-1+8-------> 4x=7
x=7/4------> x=1.75
therefore
the answer is
x=1.75
volume = PI x r^2 x h
using 3.14 for pi
volume = 3.14 x 2^2 x 3
volume = 37.7 cubic cm of wax needed
Round answer as needed
Answer:
A^8/b^10
Step-by-step explanation:
first do the parentheses first
a^4/b^5
squared
a^8/b^10
Answer:
It's answer is C. 65°
Step-by-step explanation:
we know that exterior angle of a triangle is equal to the sum of two opposite interior angle
y + y = 130° <exterior angle of a triangle is equal to the sum of two opposite interior angle >
2y = 130°
Therefore y = 65°
