Answer:
150
Step-by-step explanation:
I think that correct answer is 150
Refer to the diagram shown below.
Because ΔABC is isosceles and AB = AC, therefore
m∠C = m∠B = (3x + 5)°
The sum of angles in a triangle is 180°, therefore
2(3x + 5) + 2x - 20 = 180
6x + 10 + 2x - 20 = 180
8x - 10 = 180
8x = 190
x = 23.75°
Therefore
m∠C = 3x + 5 = 3(23.75) + 5 = 76.25°
Answer: 76.25°
Answer:
Let the unknown number be x and the other greater number be x+7
(x+7)+x=17
2x=17-7
x=5
x+7=5+7
=12
