6 0

Answer:

11. x=10, y=14.1421356237

12. x=12.124355653, y=14

Step-by-step explanation:

11. Use tan and pythagorus

tanA=opposite/adjacent

tan45=x/10

10(1)=x

x=10

a²=b²+c²

y²=x²+10²

y²=10²+10²

y²=100+100

y=√200=14.1421356237

12. Use tan and pythagorus

tanA=opposite/adjacent

tan30=7/x

0.57735026919x=7

x=7/0.57735026919

x=12.124355653

a²=b²+c²

y²=x²+7²

y²=12.124355653²+7²

y²=147+49

y=√196=14

If r = 9, b = 5, and g= −6, what does (r + b − g)(b + g) equal?
r-ruslan [8.4K]

Answer:

-20

Step-by-step explanation:

(r + b − g)(b + g)

we have fom statement:

r = 9    

b = 5

g= −6

so we have:

(r + b − g)(b + g)= (9+5-(-6))*(5+(-6))

(r + b − g)(b + g)= (14+6)*(-1)

(r + b − g)(b + g)= -20
