PEMDAS

parenthesis, exponents, mult/division, add/subtract

parenthesis: 4+0.2= 4.2

exponents: 10^2= 10×10= 100

new equation: 10-5/100×0.4(4.2)

multiply/divide: 10-(1/20)×.4×4.2

10-(0.05)(0.4)(4.2)

10-0.002×4.2

add/subtract: 10-0.0084 = 9.9916

~this feels like a wrong answer~

What is the value of x?

Lunna [17]

Answer:

x = 23 degrees

Step-by-step explanation:

sin theta = opposite side/ hypotenuse

sin x= 9/23

Take the arcsin of each side

arcsin( sinx) = arcsin (9/23)

x = arcsin (9/23)

x=23.03568411

Rounding to the nearest degree

x = 23 degrees
