Step-by-step explanation:
Answer:
The size is 37.5 degrees
Step-by-step explanation:
The total angle in the triangle is 180
Since the other two angles are congruent. it means that they are equal
Let us call each of the angles x
Mathematically,
x + x + 105 = 180
2x = 180-105
2x = 75
x = 75/2
x = 37.5

Answer:
y = 8 or y = -14
Step-by-step explanation:
Solve for y over the real numbers:
abs(y + 3) - 4 = 7
Add 4 to both sides:
abs(y + 3) = 11
Split the equation into two possible cases:
y + 3 = 11 or y + 3 = -11
Subtract 3 from both sides:
y = 8 or y + 3 = -11
Subtract 3 from both sides:
Answer: y = 8 or y = -14
