1 1/2= v + 3/4 (that's 1 and a half, not 11 over 2)<br> what is v?
Irina-Kira [14]

Answer:

The value of v is 3/4.

Step-by-step explanation:

First, you have to convert mixed number into improper fraction :

1 \frac{1}{2} \\  =  \frac{2 \times 1 + 1}{2}  \\  =  \frac{3}{2}

In order to find the value of v, you have to substract 3/4 to both sides :

\frac{3}{2}  = v +  \frac{3}{4}

\frac{3}{2}  -  \frac{3}{4}  = v +  \frac{3}{4}  -  \frac{3}{4}

v =  \frac{3 \times 2}{2 \times 2}  -  \frac{3}{4}

v =  \frac{6}{4}  -  \frac{3}{4}

v =  \frac{3}{4}

Not quite sure how to work this out
Zina [86]
you have the hypotenuse and the opposite side so you will use sin
sin58= (30/q)
multiply both sides by q
q(sin58)=30
divide by sin58 in your calculatior
q=(30/sin58)
^ I don't have a calculator with me so you will need to plug that in
