Answer:
(x-1)(x+5)=0
x=1; x=-5
Step-by-step explanation:
x²+4x=5
x²+4x+2²=5+2²
(x+2)²=3²
(x+2)²-3²=0
(x+2-3)(x+2+3)=0
(x-1)(x+5)=0
(x-1)=0 ; x=1
(x+5)=0; x= - 5
Answer: smaller angle = 17°
The angle is a right angle so the total degree of the angle would be 90°
Step-by-step:
Equation:
(4x+1)+(x-1) = 90
5x = 90
X = 18
Smaller angle:
(X-1)
(18-1)
17°
