Option C:
x = 30
Solution:
The given image is a triangle.
angle 1, angle 2 and angle 3 are interior angles of a triangle.
angle 4 is the exterior angle of a triangle.
m∠4 = 2x°,
, m∠3 = 20°
Exterior angle theorem:
<em>In triangle, the measure of exterior angle is equal to the sum of the opposite interior angles.</em>
By this theorem,
m∠4 = m∠2 + m∠3

Subtract
on both sides of the equation.

To make the denominator same and then subtract.


Multiply by
on both sides of the equation.
x° = 30°
x = 30
Hence option C is the correct answer.
Only cabinet with two silver coins is cabinet B.
The chance of choosing cabinet B is 1/3.
Thus, there is a 1/3 chance of the two cabinets contain 2 silver coins.

"FOUND THAT THE --------- IS 58
Step-by-step explanation:
Answer: x= -7
Step-by-step explanation:
subtract 8x from both sides of the equation which would leave you with 2x+18=4
then you would subtract 18 from each side of the equation leaving you with 2x= -14
the divide by 2 on both sides of the equation giving you the answer of
x= -7
Answer:
X^2 + 5x + 6
Step-by-step explanation:
(X times X) + (x times 2) + (x times 3) + ( 3 times 2)
X^2 + (2x) + (3x) + 6
combind like terms
X^2 + 5x + 6
