Answer:
Step-by-step explanation:
We will use the general area formula for finding the area of triangle when you are given information for SAS, which we have been.
, where a and b are the given side lengths and C is the included angle. You can ONLY use this when you have the info for SAS in a triangle. For us,
a = 17, b = 15 and C = 35 degrees. Filling in:

Do that on your calculator in degree mode and you'll find the area to be
73.1 meters squared
(x-1)^4 = (x-1)²(x-1)²=
=(x²-2x+1)(x²-2x+1)
& now you should know how to continue
Answer:
134
Step-by-step explanation:
1. seperate the rectangle bottom and the triangle top
2. I did the triangle first: 4×12=48÷2=24
3. the rectangle: 11×10=110
4. add the final numbers together: 110+24=134
