Answer:
x = 5
Step-by-step explanation:
6x - 3 = 3x + 12
-3x -3x
_____________
3x - 3 = 12
+3 +3
_____________
3x = 15
15 divided by 3 = 5
x = 5
You can double check this by replacing x with (5)
If it is right both sides should equal the same
6(5) - 3 = 3(5) + 12
30 - 3 = 15 + 12
27 = 27
This would prove that x = 5
Answer:
the first one
Step-by-step explanation:
To solve this problem you use the Triangle Angle Sum Theorem concept. Which means all 3 angles of a triangle add up to 180° degrees.
The formula for this concept is:
a+b+c=180°
Answer:
41
Step-by-step explanation:
This is the formula
a^2 + b^2 = c^2
35^2 + 21^2 = 1666
√1666 = 40.81...
Maybe you can estimate it to 41.
Answer:
3) 84°
Step-by-step explanation:
The angle formed by a chord and a tangent measures half of the intercepted arc.
m<A = (1/2)m(arc) = (1/2) * (168 deg) = 84 deg
Answer:
C
