Answer:
angle B=120º
Step-by-step explanation:
15+45=60
We know that all triangles have angle measures that equal 180
So 180-60=120
angle B=120º
In a triangle, the three interior angles always add to 180°
m∠B = 180 - 30 - 80 = 70°

I think laura is 10 years old and her dad is 40
X= -x over 2 (negative x as a fraction and 2 is the denominator) minus y+ (seven as the numerator over 2 as the denominator).
Solve for y by simplify both sides with inverse operations, then isolate the variable and you get, y = 3x - 1.
