Answer:
x-1+\frac{4x-3}{x^2+2x+1}
Step-by-step explanation:
Answer:
m∠k = 60°
Step-by-step explanation:
- an exterior angle of a triangle is equal to the sum of the opposite interior angles
4x + 2 + 6x - 12 = 130
to find x:
4x + 2 + 6x - 12 = 130
4x + 6x = 130 - 2 + 12
10x = 120
x = 120/10
x = 12
apply the value of x to find the measure of angle K:
k = 6*12 - 12 = 60
the answer to this system of linear equations is (3,6)
