Answer:
x = 78 degrees
Step-by-step explanation:
Let y represent the last angle in the triangle containing 79 degrees and x degrees.
Since the top and bottom lines are parallel, then angle y and angle 23 are alternate angles. Alternate angles are equal. Therefore,
Angle y = 23 degrees
The sum of the angles in a triangle is 180 degrees. It means that
Angle x + angle y + 79 degrees = 180 degrees. Therefore
x + 23 + 79 = 180
x + 102 = 180
Subtracting 102 from the left hand side of the equation and the right hand side of the equation, it becomes
x + 102 - 102 = 180 - 102
x = 78 degrees
If you increase the price 9 times which is 5 dollars more each time you get only 30 students that are willing to buy it. Any more increases will lead to no one wanting to buy it.
The answer is ASA.
Given that ∠A = ∠O, ∠W = ∠N, SW = TN, this shows that the two angles (∠A and ∠W) and the included side SW of the first triangle are equal to the two angles (∠O and ∠N) and the included side TN of the second triangle. This means that third angles ∠S and ∠T are also equal. Therefore, the two triangles ΔWAS and ΔNOT are congruent based from the ASA Postulate.
Answer:
-6
(I don’t understand what you mean by on & 5 but..)
Step-by-step explanation:
The two negatives (the -(- ) cancel each other out and make a postive, so
-18 + 12 = -6
4(2b+2)-3
8b+8-3
8b+5
the bolded is you answer
