Answer:
2.8
Step-by-step explanation:
tan = opposite / adjacent
( opposite = side opposite of the angle and adjacent = side length that is not the opposite nor the hypotenuse ( longest side ) )
we are given an angle, ∠E = 26°
tanE = x / 5.7
tan26 = x / 5.7
==> multiply both sides by 5.7
5.7tan26 = x
==> simplify
x = 2.8 ( rounded )
There are 4 hundreds 4 tens and 9 ones.
Work: 231 + 218 = 439
Hope this helps!
