Answer: Choice D) 11
----------------------------
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(35) = 9/x
x*cos(35) = 9
x = 9/cos(35)
x = 10.9869712988531 ... make sure your calculator is in degree mode
x = 11 ... rounding to the nearest tenth
Answer:
12
Step-by-step explanation:
3 x 4 = 12
3x-6+10x+15=35
10x+3x=35-15+6
13x=26
x=2
