70
this is because the bottom line has to equal 180, the angles given, 50 and 60, add up to 110, meaning the missing angle is 70 hope this helps :)
Answer:
Step-by-step explanation:
Given x^2+4x+13=0, find the complex roots. The best approach here is to use the quadratic formula. Note that a = 1, b = 4 and c = 13.
Thus, the discriminant, b^2 - 4ac, is (4)^2 - 4(1)(13) = 16 - 52 = -36, and the square root of that is plus or minus i√36, or plus or minus 6i.
plus or minus i√
The answer should be $8 if you are trying to find the unit rate. All you have to do is divide 32 by 4 and you get 8. Hope that helped.
Part A:
Let the width of the rectangle be = x inches
As given, the length of a rectangle is 3 more inches than the width so let the length of the rectangle be = x+3 inches
Perimeter is given as = 54 inches
Perimeter = ![2(l+b)](https://tex.z-dn.net/?f=2%28l%2Bb%29)
Equation becomes:
=54
![2(2x+3)=54](https://tex.z-dn.net/?f=2%282x%2B3%29%3D54)
Part B:
Solving the equation we get
![4x+6=54](https://tex.z-dn.net/?f=4x%2B6%3D54)
![4x=54-6](https://tex.z-dn.net/?f=4x%3D54-6)
![4x=48](https://tex.z-dn.net/?f=4x%3D48)
![x=12](https://tex.z-dn.net/?f=x%3D12)
Hence, the width of the rectangle is 12 inches
Length = x+3 = 12+3 = 15 inches
Hence, length of the rectangle is 15 inches.
Answer:
FGE = 180 - (14 + 78)°
= 88°
so angle GEC = 88°
4x + 88 = 180
4x = 180 - 88
4x = 92
x = 92/4
= 23
