Answer:

You use the facts about a 30, 60, 90 triangle.

Step-by-step explanation:

The angles in a triangle add up to 180.

90+30+x=180

120+x=180

x=60

This is a 30-60-90 right triangle.

The side opposite the 30 degree angle is a.

The side opposite the 90 degree angle (hypotenuse) is 2a.

The side opposite the 60 degree angle is a\sqrt{3}

We know the side opposite the 90 degree angle.

2a = 12\sqrt{3}

Divide by 2.

a=6\sqrt{3}

a is the side opposite the 30 degree angle (y)

Because we know a, we can find a\sqrt{3}.

6\sqrt{3 } (\sqrt{3})

The square roots cancel, leaving 3.

6 times 3 is 18.

Therefore, the side opposite the 60 degree angle (x) is 18.

Harry invests £6000 in a savings account.
zysi [14]

Step-by-step explanation:

here,

principal (p)=£6000

Rate (R)=. 3.4%

time (t)=3 yrs

now,

total investment is compound amount i.e CA

here,

CA = p(1  + \frac{r}{100} ) ^{t}

=£6000(1+3.4/100)^3

=£6633.044

here he will get his total investment as £6633.044 in compound interest of 3.4%

➷ Angles on a straight line equal 180 degrees:

5k - 3 + 9 + k = 180

Simplify:

6k + 6 = 180

Subtract 6 from both sides:

6k = 174

Divide both sides by 6:

k = 29

Help plz I'm desperate ​
lutik1710 [3]

<u>Anna:</u>

1st month = 18 + \frac{3}{4} = 18\frac{3}{4} inches

2nd month = 18\frac{3}{4} + \frac{3}{4} = 19\frac{1}{2}

3rd month = 19\frac{1}{2} + \frac{3}{4} = 20\frac{1}{4}

4th month = 20\frac{1}{4} + \frac{3}{4} = 21

5th month = 21 + \frac{3}{4} = 21\frac{3}{4}

<u>Grace:</u>

Because Anna is \frac{9}{4} inches shorter than Grace, we can start the count from the third month:

1st month = 20\frac{1}{4}

2nd month = 21

3rd month = 21\frac{3}{4}

4th month = 21\frac{3}{4} + \frac{3}{4} = 22\frac{1}{2}

5th month = 22\frac{1}{2} + \frac{3}{4} = 23
