Answer:

Bottom left angle is 19°

Bottom right angle is 28°

Top angle is 133°

Step-by-step explanation:

Since all angles of a triangle add up to 180° we know x + 7x + x+9=180. then we combine like terms to get 9x+9=180. Next, we do inverse operation to find X. First subtract 9 from both sides of the equation to get 9x=171 then divide 9 from both sides to get x=19. No that we know x, we can find the values of the angles by putting in 19 for x. Bottom left angle is 19°, bottom right angle is 28°, top angle is 133°.

Answer:

x=19º

x+9=28º

7x=133º

Step-by-step explanation:

x+9+x+7x=180

9x+9=180

9x=180-9

9x=171

x=19

Margaret deposits $1,000 in a savings account that pays 1.4% interest compounded
ozzi

Answer:

The balance after 1 year is;

$1,014.05

Step-by-step explanation:

To do this, we use the compound interest formula

That will be ;

A =P (1 + r/n)^nt

A is the amount generated which we want to calculate

r is the rate = 1.4% = 0.014

P is the amount deposited = $1,000

n is the number of times it is compounded annually which is 2 (semi-annually means 2 times in a year)

this the number of years which is 1

we have this as:

A = 1,000( 1 + 0.014/2)^(2*1)

A = 1,000(1 + 0.007)^2

A = 1,000(1.007)^2

A = $1,014.05
