A)
a•b=20
a=b
a=b=square root from 20

c•d=30
c=d
c=d=square root from 30

a^2+c^2=d^2
20+30=d^2
50=d^2
d=square root from 50

Area=square root from 50•square root from 50=50

B)
a•b=16
a=b
a=b=square root from 16=4

c•d=36
c=d
c=d=square root from 36=6

a^2+c^2=d^2
4^2+6^2=d^2
16+36=d^2
d=square root from 52

Area=square root from 52•square root from 52=52

Answer:

1. 6.4 meters of streamers left to make pompoms

Find the exact value of sin (x-y) if sinx=4/9 and siny=1/4
Svetach [21]

Answer:

sin(x - y) = 0.21

Step-by-step explanation:

we have the sin values which we need to get cos values

sin (A-B) = sin A cos B - sin B cos A

sin² A + cos² A = 1

sin x = 4/9

cos² x = 1 - sin² x = 1 - 16/81 = 65/81

cos² x = 65/81

cos x = √65/9

sin y = 1/4

cos² y = 1 - sin² y = 1 - 1/16 = 15/16

cos² y = 15/16

cos y = √15/4

sin(x − y) = sin x cos y - sin y cos x

sin(x - y) = 4/9 √15/4 - 1/4 √65/9

sin(x - y) = (4√15-√65)/36

sin(x - y) = 0.21
