Answer:

61°

Step-by-step explanation:

(x+18)°=(4x-15)°alternate angles, because BC is parallel to AD

x°+18°=4x°-15°

18°+15°=4x°-x°

33°=3x°

33°/3°=3x°/3°

11=x

angle ABD

90°-(x+18)°. the sides of a rectangle meet at 90°

90°-(11+18)°

90°-(29)°

90°-29°

61°

What is the 100th term in the sequence 23, 21, 19, 17, 15 ....?<br> PLEASE HELP

Volgvan

Hey there!

We can see we are subtracting 2 every time, and we have 95 terms left fo figure out, so we multiply 95 by 2 and get 190, then subtract that from 15.

15 - 190 = -175, therefore, that's the the 100th term.

Have a terrifcly amazing day!
