Answer: 49°, 49°, 82°
<u>Step-by-step explanation:</u>
Let x represent the base angles
then 2x - 16 is the vertex angle.
Triangle Sum Theorem states that the sum of the angles is 180°
(x) + (x) + (2x - 16) = 180
4x - 16 = 180
4x = 196
x = 49
Base angles: x = 49
Vertex angle: 2(49) - 16 = 82
Answer:
A
Step-by-step explanation:
Answer:
(x+5)^2
Step-by-step explanation:
(x+5)^2 Using the foil method 5+5=10 and 5x5=25
We have to find the equation for three times a number is three more than twice the number.
Let the number is x.
Three times a number = 3x
Three more than twice the number. = 3+2x
These two equations should be equal.
Hence, we have

Therefore, the equation 3x = 3 + 2x can be used to find the unknown x.
A is the correct option.
