Answer: x = 5
Step-by-step explanation: This is an isosceles triangle, which means two sides are equal in length and two angles are equal in measurement.
Line BA = Line BC
Similarly, Angle A = Angle C
Angle A plus Angle C equals 146°
Also the sum of the interior angles of a triangle is 180°
Therefore, 146 + (6x + 4) = 180
Subtract 146 from both sides of the equation
6x + 4 = 34
Subtract 4 from both sides of the equation
6x = 30
Divide both sides of the equation by 6
x = 5
The answer is D. The easiest way to see this is by using the FOIL method.
First
Outside
Inside
Last. So the first is x2, the outside is -10x, the inside is -7x, and the last is 70. So it would be x2-17x+70
Answer:
x = 6
Step-by-step explanation:
When 2 chords of a circle intersect then the product of the parts of one is equal to the product of the parts of the other, that is
2x = 3 × 4, that is
2x = 12 ( divide both sides by 2 )
x = 6
Answer:
930
Step-by-step explanation:
600% of x = 5580
6x = 5580
x = 5580/6
x = 930
