Answer:
Answer z = 55
Step-by-step explanation:
Remark
I think you have to assume that the horizontal line is a straight line. If that is so, the other line, the one that looks like it is going up and to the left, cuts that horizontal line in such a way that the angles are supplementary. Supplementary angles are angles that add up to 180 degrees.
Equation
2z - 10 + 80 = 180 Combine the like terms on the left.
Solution
2z + 70 = 180 Subtract 70 from both sides.
2z + 70 - 70 = 180 - 70 Combine
2z = 110 Divide by 2
2z/2 = 110/2 Do the division
z = 55 Answer
Answer:
z=55
Step-by-step explanation:
The two angles form a straight line which is 180 degrees
80 + 2z-10 = 180
Combine line terms
70 +2z = 180
Subtract 70 from each side
70-70 +2z= 180 -70
2z = 110
Divide by 2
2z/2 = 110/2
z = 55

Step-by-step explanation:
hello : note 297 no 279
297 =3 ×99
99 = 3 ×33
33=3 ×11
this the geometric sequence. ( comon : 3)
the nth term is : An = A1 × r^n when : r = 3 and A1 =11
if n = 19 A19 = 11×3^19
