Given: △abc, ab=5 2 m∠a=45°, m∠c=30° find: bc and ac

BC = 5 m

AC = 3.66 m

Step-by-step explanation:

Using the sin rule,

AB×sin C = BC×Sin A

5√2 × Sin 30 =  a sin 45

3.5355 = BC sin 45

BC = 3.5355/sin 45

    = 5 m

AC × sin 105 = 5√2 × sin 30

AC = 3.5355/sin 105

      = 3.66 m

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
