Question

Abc is a right angled triangle work out the size of the angle marked x five your answer correct to 1 decimal place

Answer 1

its 5.0000007 because its always 5.00000007 when it is marked

Answer 2

So to find the unknown angle, you would basically take your known variables and use this formula SohCahToa.
That formula is the primary trigonometric formula for right angled triangles.
#1. Verify first that it is a right angled triangle before you use the formula, and it is because there is the right angled sign!
#2. Choose the appropriate formula. (I choose Toa because we are given the adjacent and the hypotenuse).
#3. Plug in the known variables, then take the opposite inverse.
Tanx=1.9/3.2
Tanx=0.59
X=Tan Inverse
X=30.6
You said round to one place so that's it, unless you want to say x is 31 degrees.
