If you angle at the bottom is 50 that makes the opposite one 50 to and when there is a small square like at the top angle it means it is a 90° angle.
Since every triangle equals 180° you subtract 140 which is the 2 angles added together and the last angle would be 40°.
Answer:
10/20 or 1/2 it is 50% chance that she pass and 50% that she fail
Step-by-step explanation:
Math pretty much has its own language. In an expression, u have to " break it apart " to make each term
one more then the product of a number and 7 decreased by 5...
" product " means multiply.....so the product of a number and 7 would be 7n.
one more then the product....(7n + 1)....." decreased" means subtract....
so ur expression is : (7n + 1) - 5
(7n + 1) - 5....when n = 6
(7(6) + 1) - 5 =
43 - 5 =
38 <==
