Answer:
option D
Step-by-step explanation:
x/-3≤3
multiply by (-1) on both sides
x/3≥-3
x>=-9
Answer:
-6y = 70x = 3
Step-by-step explanation:
-6x - 5y= 64x+ y=3
---------------------------
-y - y
---------------------------------
-6x -6y = 64x = 3
------------------------------------
+6x +6x
-------------------------------------
-6y = 70x = 3
we know that
In the right triangle ABC
∠
∠
------> by complementary angles
so
Step 
Find the measure of angle B
we know that

in this problem

so

Step 
Find the measure of angle A

therefore
the answer is the option
35.5° and 54.5°
