Answer:

B=34.2

C=105.8

c=12.0

Step-by-step explanation:

find B using the sine rule

(sin40÷8)=(sinB÷7)

rearrange

sin B= (sin40x7)÷8

sin B=0.562

make sure to use your calculator

then press shift sin to find B

B= 34.2°

to the nearest tenth means to 1 decimal place

sum of angles in a triangle is 180

so 180-(40+34.2)=105.8°=C

use sine rule again to find c

(sin105.8÷c)=(sin40÷8)

rearrange

c= (sin 105.8x8)÷sin40

c=12.0

Answer:

Y = 0

Step-by-step explanation:

Both functions have

maximum of $\frac{2}{3}$

midline is then the average of these

( $\frac{2}{3}$ - $\frac{2}{3}$ ) ÷ 2 = 0 ÷ 2 = 0

midline has equation y = 0 ( that is the x- axis )
