Answer:
a1= -19, a2= 9
Step-by-step explanation:
step 1. Add 5 + 9 /a +5/ = 9+5
step 2. Use the absolute value definition, rewrite the absolute value equation as two separate equations. a+5=14 a+5= -14
step 3. a=9 a+5= -14
step 4. a= 9 a= -19 the equation has 2 solutions
a¹ = - 19, a²= 9

Answer:
139
Step-by-step explanation:
Inside angles of a triangle = 180 degrees

180 - 139 = 41
unknown interior angle = 41 degrees
So m<1 = 139
(Or just add the two interior angles together)
