Here's the solution,
The given triangle is a right angled triangle,
So, by Using Trigonometry :
=》
=》
=》
=》
hence, value of x = 6.5 units
Use PEMDAS to solve
(Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction)
Solve parenthesis first
<span>(1/3+9) x ( 8-3)
</span>28/3 x 5
Use Multiplication
28/3 x 5 ≈ 4.7
After rounding 4.7 should be your answer
Answer: 2.625
Step-by-step explanation:
All you have to do is divide 5 by 8 which gives you .625 and then you put the 2 in front of the decimal amd you get your answer.
