I really need help please

∠ A = 60°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinA = = = , thus

∠ A = ( ) ≈ 60°

------------------------------------------------

Using the cosine ratio in the right triangle

cosR = = = , thus

∠ R = ( ) ≈ 36.9° ( to 1 dec. places )

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

x = 12

y = 1

for the points!
