Answer:
65 deg
Step-by-step explanation:
Recall that interior angles of a triangle must add up to 180 deg.
hence
x + 68 + 47 = 180
x = 180 - 68 - 47 = 65 deg
Answer:
y = -15/17x + 1
Step-by-step explanation:
15x + 17y = 17
17y = 17 - 15x
y = 1 - 15/17x
y = -15/17x + 1
Answer:
x = 23°
Step-by-step explanation:
Note: Complementary angles measure 90°
3x + (x - 2)° = 90°
=> 3x + x - 2° = 90°
=> 4x - 2° = 90°
Add the additive inverse of -2 to both sides of the equation
i.e 4x - 2° + 2° = 90° + 2°
=> 4x = 92°
Divide both sides of the equation by the coefficient of x which is 4
=> 4x/4 = 92°/4
x = 23°
Answer:
80 is 50% of 160.
Step-by-step explanation:
In order to find this, we take the whole number and divide by the percentage that it represents. This gives us the number we are looking for.
80/50%
80/.50
160
