The sum of two supplementary angles is 180 degrees.
A+B=180.
80+B=180
B= 180-80
B=100
Revenue from property taxes is used to fund all the services the municipal government provides us with, such as building a new park in the neighbourhood.
Answer:
x=15√2 y=90 degrees.
Step-by-step explanation:
Thanks to the Pythagorean Theorem we know that with any right triangle, A^2+B^2=C^2. In this case we can use 15^2+15^2=sqrt of 450. The square root of 450 is 15 times the square root of 2. Thus x=15√2. Now we need to find y. All angles in a triangle add up to 180 so if we have 45+45+y=180 then y=90.
