Alright here we go
First we need to find the upper angle by doing 180 - 143 = 37. Because it’s a straight line.
Second we need to find angle ADC
a triangle has 180 degrees, and we have 38 and 37.
180 - (38+37) = 105
then we find what the question wants:
180 - 105 = 75 degrees
Solve your system of equations.
2x+y=1;4x+2y=−1
Solve 2x+y=1 for y:
2x+y+−2x=1+−2x(Add -2x to both sides)
y=−2x+1
Substitute (−2x+1) for y in 4x+2y=−1:
4x+2y=−1
4x+2(−2x+1)=−1
2=−1(Simplify both sides of the equation)
2+−2=−1+−2(Add -2 to both sides)
0=−3
Answer: No solution. C)
Answer:
AC = 52
Step-by-step explanation:
Add the segment lengths together.
AB + BC = AC
22 + 30 = 52
