First let's find y. We know the sum of angles equals 180, so if we add the angles of ABC, we'd get 180.
30+y+80+y=180
110+2y=180
2y=70
y=35
You could solve x ,but the only response with y=35 is c. But to solve for x, you'd ad 35 35 and xwhich would equal 180.
35+35+x=180
70+x=180
x=110

Step-by-step explanation:
Here's an example to help you:
(2×4) ÷ (1×2)=
8÷2.
Your basically just trying to put the expression with its simplest form.
Answer:
1792
Step-by-step explanation:
given,
f (n) = 4 f (n - 1)
here,
f(2) = 4 f ( 2-1)
= 4 f ( 1 )
= 4. 7
= 28
then,
f(3) = 4 f ( 3-1)
= 4 f ( 2)
= 4. 28
= 112
again,
f (4) = 4 f ( 4-1)
= 4 f ( 3)
= 4.112
=448
at last,
f ( 5) = 4 f ( 5-1)
= 4 f ( 4)
= 4. 448
= 1792
