Answer:
bc= 7
Step-by-step explanation:
Answer:
1/2 or .5
Step-by-step explanation:
solve for x in the bottom equation
x = 4 - 8y
substitute the equation for x back into the top equation
4(4- 8y) - y = 3y + 7
solve for y
36y = 9
y = 1/4
substitute y back into the equation solving x
x = 4 - 8(1/4)
solve for x
x = 4 - 2
x = 2
xy = 1/4 * 2
xy = 1/2
Since we are asked to find DF, and we are given an angle and the side opposite to it, we can use the sine function to find DF.
let x be the length of side DF.
sin(32)= 17/x
x= 17 / sin(32)
x= 32.08
approximately 32.1
Answer:30,41,66
Step-by-step explanation:
(X+7)+(2x-5)+(3x-3)=137
Solve for x
X=23 cm
Sides are 23+7=30
2*23-5=41
3*23-3=66
