Answer:
A = 77.32
Step-by-step explanation:
Since this is a right triangle we can use trigonometric functions
sin = opposite side/ hypotenuse
sin A = 80/82
sin A =40/41
Take the inverse sin of each side
sin^-1 (sin A ) =sin ^-1 (40/41)
A =77.31961651
Rounding to the nearest hundredth
A = 77.32
We will use the distributive property. -4 times 9z=-36z -4 times -2=8 so we have -36z+8 as our answer
