Answer:

38.3

Step-by-step explanation:

subtract 45 from each side

6x/2 = 160-45

6x/2 = 115

multiply each side by 2

6x= 115*2

6x= 230

divide each side by 6

x= 230/6

x= 38.3

Can you deposit 1750 into investment account that will produce 6.05% annual interest the money was left in the car for two years

PSYCHO15rus [73]

Step-by-step explanation:

Find out how much you get money from the annual interest:

100% = 1750

1% = 1750 ÷ 100 = 17.5

6.05% = 17.5 x 6.05 = 105.87

Find out how much you get from interest in 2 years.

105.87 x 2 = 211.74

Pls help:Find all the missing elements:

Yuliya22 [10]

Answer:

Step-by-step explanation:

In order to find B we must first angle C

To find angle C we use the sine rule

That's

$\frac{ |a| }{ \sin(A) } = \frac{ |c| }{ \sin(C) }$

From the question

a = 15

A = 70°

c = 14

So we have

$\frac{15}{ \sin(70) } = \frac{14}{ \sin(C) }$

$\sin(C) = \frac{14 \sin(7 0 ) }{15}$

$C = \sin^{ - 1} ( \frac{14 \sin(70) }{15} )$

C = 61.288

<h3>C = 61.3° to the nearest tenth</h3>

Since we've found C we can use it to find B.

Angles in a triangle add up to 180°

To find B add A and C and subtract it from 180°

That's

A + B + C = 180

B = 180 - A - C

B = 180 - 70 - 61.3

<h3>B = 48.7° to the nearest tenth</h3>

To find b we can use the sine rule

That's

$\frac{ |a| }{ \sin(A) } = \frac{ |a| }{ \sin(B) }$

$\frac{15}{ \sin(70) } = \frac{ |b| }{ \sin(48.7) }$

$|b| = \frac{15 \sin(48.7) }{ \sin(70) }$

b = 11.9921

<h3>b = 12.0 to the nearest tenth</h3>

Hope this helps you
