Answer:
<A = 67
Step-by-step explanation:
The three angles of a triangle add up to 180 degrees. We know a right angle is 90 degrees.
<A + <B + <C = 180
3x-8 + 90 + x-2 =180
Combine like terms
4x-10+90 = 180
4x+80 =180
Subtract 80 from each side
4x+80-80=180-80
4x=100
Divide each side by 4
4x/4 = 100/4
x=25
But we want to know <A
<A = 3x-8
Substitute x=25
=3(25) -8
=75-8
= 67
Standard Form has many faces including polynomial, decimal, equation and etc. According to your question transforming that in polynomial for Two hundred million would be 200,000,000 or 2 x 10^8 in scientific notation
Answer:
16 pages
Step-by-step explanation:
1 hour= 2 pages written of notes
so 8 hours of notes = 8x2=16 pages
The question would help if there were a picture of the problem
however I can say that it should always add up to 180 and subtracted by the interior sum
-8x+4=36
-4 -4
-8x=32
divde be -8 on both sides
x=-4
