Answer:
$15.75
Step-by-step explanation:
y × 100 = 5 × 15
100y = 75
100y ÷ 100 = 75 ÷ 100
y = 0.75
$15 - $0.75
$14.25
y × 100 = 10 × 15
100y = 150
100y ÷ 100 = 150 ÷ 100
y = 1.5
$14.25 + $1.50
$15.75
Answer:
Step-by-step explanation:
take 30 degree as reference angle
using cos rule
cos 30=adjacent/hypotenuse
/2=7
/y(do cross multiplication)
14=y
14/
=y
14=y
for x
using pythagorsa theorem
H^2=P^2+B^2
14^2=X^2+(7)^2
196=X^2+147
196-147=X^2
49=X^2
=X
7=X
