Answer:
x = 22 degrees
Step-by-step explanation:
Since this is a right angle and both angles added together will equal to 90degrees this means that:
(3x-5) + (x+7) = 90
(first, remove the brackets)
3x-5+x+7 = 90
( add the numbers together and the term x together)
( 3x+x ) + ( -5+7 ) = 90
4x + 2 = 90
(subtract 2 from both sides)
4x = 88
(divide by 4 from both sides)
x = 22
so the measure of x = 22 degrees
Answer:
rational function
Step-by-step explanation:
That would be a "rational function;" it's the "ratio" of two polynomial functions, with the understanding that the denominator may not be zero.
Answer:
Perimeter of a triangle = 2*(length + breadth)
SO = 2*18+41
= 77 is the perimeter
Answer:
I know it.
Step-by-step explanation:
triangles always add up to 180 degrees so add 43 and 32 together and you will get 75 so then you take 75 off 180 and you will get 105
that's your answer
A = 105
Answer:
a^3-125
Step-by-step explanation:
(a-5)(a^2+5a+25)
a^3+5a^2+25a-5a^2-25a-125
a^3+5a^2-5a^2+25a-25a-125
a^3-125
