What is the best first step in solving the following equation 10+x/3=1

kykrilka [37]

Answer:

Do the Division first.

Step-by-step explanation:

If you remember PEMDAS, or BOMDAS if you prefer, division and multiplication comes before addition and subtraction.

x, in this case, would equal -27. (-27 ÷ 3 = -9) then add 10

(-9 + 10 = 1)

What is the measure of an angle whose sine is√3/2 ? 60 45 30

dem82 [27]

ANSWER

The required angle is
$60 \degree$

EXPLANATION

Let the angle whose sine is
$\frac{ \sqrt{3} }{2}$
be
$x \degree$

Then

$\sin(x \degree) = \frac{ \sqrt{3} }{2}$

We take the inverse sign of both sides to obtain,

$x = \sin ^{ - 1} ( \frac{ \sqrt{3} }{2} )$

We use our scientific calculator to evaluate and obtain,

$x = 60 \degree$
