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:
A 19 inch tv cost $89
Step-by-step explanation:
37 inch tv : 400 = 5x - 45
19 inch tv : x
We have the equation:
5x - 45 = 400
5x = 445
x = 89
See photo for solution and mark me as brainliest if i helped :)
A: although it seems like they are forming a 90º angle, they actually add up to a 89 º angle and therefore are not complementary
B: see photo
