Answer:
X1=(-3+7)÷2=2---> X1=2-->First root
X2=(-3-7)÷2=-5---> X2= -5-->Second root
Step-by-step explanation:
X^2=-3X+10 you need to change the order of this equation
X^2+3X-10=0---> You do this in order to do BHASKARA
then you do BHASKARA
-3(±√9-4·1·-10)÷2·1
X1=(-3+7)÷2=2---> X1=2-->First root
X2=(-3-7)÷2=-5---> X2= -5-->Second root
Answer:
Step-by-step explanation:
try the numbers -3 -2 1 and 3
Answer:
B
Step-by-step explanation:
The 115° angle is adjacent to both unknown angles in the triangles, thus
unknown angles = 180° - 115° = 65°
The sum of the 3 angles in a triangle = 180°, thus
∠ 1 = 180° - (65 + 80)° = 180° - 145° = 35°
∠ 2 = 180° - (65 + 85)° = 180° - 150° = 30°
