Answer:
46.5
Step-by-step explanation:
i divided 93 by 2 and got 46.5
hope this helps :)
The angles are set to equal to eachother since alternate interior angles are congruent
so 6x+5=4x+45
Solve for X
-5 from both sides
6x=4x+40
-4x both sides
2x=40
÷2 both sides
X=20
Now plug in the answer for X in angle A to figure out what degree angle A is 6x+5
6 (20)+5
120+5
I believe the answer would be d .
Answer:
Step-by-step explanation:
arithmetic sequence: 60,68,76,......
a = 60
d = 68 - 60 = 8
an = a + (n-1)*d
a20 = 60 + 19 * 8
= 60 + 152
= 112
There are 112 seats in the 20th row
