Answer:
AUBUC= { a,b,c,d,e,f,g,h,i,o,u}
Answer:
Step-by-step explanation:
This is right triangle trig. The side opposite the x is 8, and the side adjacent to the x is 5. The tangent ratio uses those sides. We need to find what angle has a tangent of 8/5. To do this, make sure your calculator is in degree mode. Then hit "2nd" then tan and you will see tan with a little -1 and a parenthesis. Enter 8/5 and hit "enter" and you will get an angle measure of 57.9946. Rounded to the nearest degree this is 58 degrees. That's your answer!
2/3 of a right triangle is 60 degrees. Then x + (x+20) + 60 = 180 total.
2x + 80 = 180, so 2x = 100 and x = 50. The angles are 50, 70 and 60 (degrees)
