2 onea and 8 tens is a way to express it
Answer:
x=4 x=-1
Step-by-step explanation:
x^2-3x-4=0
x^2-4x+x-4=0
x(x-4) + 1(x-4)=0
x+1=0
x=-1
x-4=0
x=4
Answer:
x=52
Step-by-step explanation:
One of the properties of parallelograms is that angle A = Angle C
5y-54 = 3x eq1
Another property of parallelograms is that angle A + angle B = 180 degrees
5y-54+2y-60 = 180
7y = 180+114 = 294
y = 42
Putting this value in eq1
3x = 5*42-54 = 210-54 = 156
x = 52
Answer:
105°
Step-by-step explanation:
Measure of the third angle
= 180° - 18° - 57° (angle sum of triangle)
= 105°
