Answer:
1=163 degrees
2=×=10 degrees
3=×=3
Step-by-step explanation:
54x+1+9x-10=180 we are using this expression because alternate angles add up to 180 degrees
54x+9x+1-10=180
63x-9=180
63×=180+9
63×=189
63×÷63×=189÷63×
X=3
Angle in bold print is (54x+1)
54×3=162
162+1=163 degrees
No.2 Find x
7x+35+x+65 =180
7x+x+35×65=180
8x+100=180
8x=180-100
8x=80
8x÷8x=80÷8
X=10 degrees
No.3 Find x
54x+1+9x-10=180
54x+9x+1-10=180
63x-9=180
63x=180+9
63x=189
63x÷63x=189÷63
X=3
I hope I was of help

Answer:
D
Step-by-step explanation:
-d + 2 < -1
-16 + 2 < -1
-14 < -1, which is true since -14 is less than -1
C. the total price depends on the number of crates
Complementary angles are those angles whose sum of the measures of angles is 90 degrees.
Supplementary angles are those angles whose sum of the measures of angles is 180 degrees.
Let us consider the first pair of angles,
1. 

Therefore, it is neither a pair of complementary angles nor supplementary angles.
2. 

Therefore, it is a pair of supplementary angles.
3. 

Therefore, it is neither a pair of complementary angles nor supplementary angles.
4. 

Therefore, it is a pair of complementary angles.
