Answer:

120

Step-by-step explanation:

1. Find the value of x.

The angles in a triangle have a sum of 180 degrees. To find x, add up the other two inside angles and subtract the sum from 180.

87 + 33 = 120

180 - 120 = 60 degrees.

x = 60

2. Angle y is supplementary to angle x, meaning that the sum of the two angles equals 180.

180 - 60 = 120

y = 120

You can use Pythagorean theorm to solve.

a^2 + b^2 = c^2
C = 3959 + 2.9 = 3961.9

x = ???? = a
b = 3959
Plugin our data.
a^2 + b^2 = c^2
a^2 + 3959^2 = 3961.9^2
a^2 + 15673681 = 15696651.61
a^2 = 22970.61
\sqrt{a^2} = sqrt{22970.61}
a = 151.560
x = 151.560
x = 151.6

£980 is divided between Caroline, Sarah & Gavyn so that Caroline gets twice as much as Sarah, and Sarah gets three times as
Nitella [24]

Sarah has received £ 294

<u><em>Solution:</em></u>

Given that £980 is divided between Caroline, Sarah & Gavyn

Let "c" be the amount received by caroline

Let "s" be the amount received by sarah

Let "g" be the amount received by gavyn

<em><u>Caroline gets twice as much as Sarah</u></em>

amount received by caroline = twice as much as Sarah

amount received by caroline = 2(amount received by sarah)

c = 2s ---- eqn 1

<em><u>Sarah gets three times as much as Gavyn</u></em>

amount received by sarah = three times as much as Gavyn

amount received by sarah = 3(amount received by gavyn)

s = 3g ------- eqn 2

Given that total amount is 980

c + s + g = 980 --- eqn 3

<em><u>Let us solve eqn 1, 2, 3 to get values of "c" "s" "g"</u></em>

From eqn 2,

g = \frac{s}{3}  --- eqn 4

Substitute eqn 1 and eqn 4 in eqn 3

2s + s + \frac{s}{3} = 980\\\\\frac{6s + 3s + s}{3} = 980\\\\6s + 3s + s = 980 \times 3\\\\10s = 2940\\\\s = 294

Thus sarah has received £ 294
