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

PLEASE HELP ASAP! A mountain climber is at an altitude of 2.9 mi above the earth’s surface.

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

Solution:

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

Caroline gets twice as much as Sarah

amount received by caroline = twice as much as Sarah

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

c = 2s ---- eqn 1

Sarah gets three times as much as Gavyn

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

Let us solve eqn 1, 2, 3 to get values of "c" "s" "g"

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
