A=1/2b(h) this is the formula to find the area of a triangle
Answer:
ok so u know that all triangles in the inside are equal to 180
Step-by-step explanation:
1. 180-162= 18 angle a is 18, now to solve for b 180-122-18=40, angle b is 40
2.180-171=9 angle a is 9, now to solve for b 180-128-9=43, angle b is 43
3.180-35-22=132 angle c is 132, now to solve for angle d 180-22=158, angle d is 158
4. 180-20-29=131 angle c is 131, now to solve for angle d 180-20=160, angle d is 160
Answer:
Amy's yearly salary in 2011 was $27,800
Step-by-step explanation:
we have
where
x ---> is the number of years since 2007
y ---> Amy's yearly salary in dollars
To find out what was her salary in 2011, first determine the value of x
substitute the value of x in the equation above
therefore
Amy's yearly salary in 2011 was $27,800
3x - 2 = 7
3x = 7 + 2
3x = 9 (divide both sides by 3 to get x)
3x/3 = 9/3
x = 3
