Answer:
52 or 28
Step-by-step explanation:
An isosceles has 2 congruent angles.
There are 2 possibilities:
A) There are two 76-deg angles and one angle of a different measure.
76 + 76 + x = 180
x = 28
B) There are two congruent angles, and 76 is the non-congruent angle.
x + x + 76 = 180
2x = 104
x = 52
Answer: 52 or 28
It would be option D because a dilation means an increase in size, where as a translation, rotation, and reflection are all movements that does not increase it size, so it will remain congruent

Answer:
1
Step-by-step explanation:
2x^2 + x -1 = 2
2x^2 + x-1-2 = 0
2x^2 + x -3 = 0
2x^2 -2x + 3x-3 = 0
2x(x-1) + 3(x-1) = 0
(2x + 3)(x-1) = 0
2x + 3 = 0
or x-1 = 0
x = -3/2 or 1
Answer:
x=150 degrees
Step-by-step explanation:
You know that the sum of the angles in a triangle is 180 degrees, so to find the missing angle in the triangle, subtract 180 from the sum of the other 2 angles: 180-(52+98)=180-150= 30 degrees.
You also know that the sum of supplementary angles is 180, and there are 2 supplementary angles. since we just found one of the angles, all we need to do is subtract 30 degrees from 180 degrees: 180-30= 150 degrees. (x is 150 degrees)
