Answer:
-86.07
Step-by-step explanation:
Theres a negative 86 and a 7 over 100.
115 degrees because there are 180 degrees in a triangle so let the missing angle in the trinagle be x. Then we have x+75+40=180. Solving for x and subtracting that from 180 (supplementary angles) we get 115 degrees.
Answer:
x = 30°
y = 30°
Step-by-step explanation:
By inscribed angle theorem:

The answer is 20000000000 1 plus 1 is two and 2 times 10000000000 is 20000000000
