6 tens is the same as 60 so....
60 x 10 = 600
Answer: 90 degrees
Step-by-step explanation:
Complementary angles add up to 90 degrees. Since a triangle has 180 degrees total, the other angle is 90 degrees
Answer:
y=107
x=73
z=73
Step-by-step explanation:
y and 107 are vertical angles, which means that they're the same value because they're vertically across from each other.
107 and x are supplementary angles, so x=180-107 or 73.
x and z are also vertical angles, so x=z=73.
Answer:
2x+9=12x-21
-2. -2
9=10x -21
+21 +21
30=10x
Divide by 10 on both sides
30/10
x=3
Step-by-step explanation:
Answer:
2x - 6y = 18
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
x = 2y + 6
Multiply through by 3 to clear the fraction
2x = 6y + 18 ( subtract 6y from both sides )
2x - 6y = 18 ← in standard form
