Division → Multiplication → Addition → Subtraction
- B stand bracket
- O stand of
- D stand division
- M stand Multiplication
- A stand for addition
- S stand for subtraction
Use pythagorean theorem
a^2 + b^2 = c^2
fill in known values
12^2+9^2 =c^2
simplify
144 + 81 = c^2
225 =c^2
square both sides
15 = c= hypotenuse
Answer:
x = 17.6
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj / hyp
cos 51 = x /28
28 cos 51= x
x=17.62097
To the nearest tenth
x = 17.6
