Answer:
measure of two unknown angles are 35.7° and 75.4°
measure of one unknown side is 16.6 inches
Step-by-step explanation:
i used law of sines to find the angle opposite 10 inch side
sin 68.9/16 = sinФ/10
Ф = 35.7°
then is added 35.7 and 68.9 and subtracted the sum from 180° to get the measure of the third angle, 75.4°
i used law of sines again to find the measure of the third side
sin 68.9/16 = sin 75.4/x
x = 16.59
The top number would be 288. It's upside down btw
O=orange
a=apple
equation 1
3o+a=$1.86
a=$1.86-3o
use a=$1.86-3o in equation 2
equation 2
2o+3a=$2.15
2o+3($1.86-3o)=$2.15
2o+$5.58-9o=$2.15
$5.58-7o=$2.15
$5.58=$2.15+7o
$3.43=7o
$0.49=o
then use $0.49=o for equation 1.
equation 1
3($0.49)+a=$1.86
$1.47+a=$1.86
a=$0.39
so an apple is $0.39.
