Answer:
-1. is -3/7
Step-by-step explanation:
6×-4/11*7 ÷ (4/3×6/11)
-24/11×7 ÷ (4/3×6/11)
-24/77 ÷ (4/3×6/11)
-24/77 ÷ (24/3×11)
-24/77 ÷ 24/33
-24/77 × 33/24
-1/77 × 33
-33/77
-3/7
Answer:
a= 30
b=60
c=105
Step-by-step explanation:
A forms a vertical angle with another angle that measures 30 degrees, therefore,
a= 30 degrees.
Since a is 30 degrees and a and b are in the same triangle with a 90-degree angle and all interior angles in a triangle equal 180 degrees.
Then, 30+90+b=180
120+b=180
b=60
Angle c and an angle that equals 75 degrees are supplementary. meaning that they add up to 180 degrees.
180-75=c
105=c
Answer is G. It won’t let me post answer unless it has 20 characters lol
