Answer:
is there like a picture of the question?
let 2nd angle = x
then 1st angle = 2x-15
then you have 90 = x + 2x-15
2x +x = 3x
so now 90 = 3x-15
add 15 to each side
105=3x
x = 105/3 = 35
1st angle = 35 degrees
2nd angle = 2(35) - 15 = 70-15 = 65
Answer:
7; not a factor
Step-by-step explanation:
2x³ - x² - 4x² + 2x + 6x - 3 + 7
x²(2x-1) - 2x(2x-1) + 3(2x-1) + 7
7 is the remainder.
Hence, not a factor
Answer:
x = 0.5
Step-by-step explanation:
2x - 3 = - 2 ( add 3 to both sides )
2x = 1 ( divide both sides by 2 )
x =
= 0.5
Answer:
B
Step-by-step explanation:
- divide the given polygon into two (a square and a trapezium
- area of trapezium=1/2(a+b)×b 1/2(12+6)×12 ans 108square unit
- area of a square=s×s 12×12 =144square unit
- add 108+144=252square unit
