If this is supposed to be
Then this can simply be reduced to
by the double angle formula for cosine
5+5=10+20=30 :) that’s your answer
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
Answer:
I can't even see the picture. I'm sorry.
Step-by-step explanation:
9 times 12 is 108. so 42/108=21/54
