Question

find the measure of angle x.
A.75
b.37.5
c.52.5
d.105

Answer 1

is it a?

Answer 2

37.5?

Answer 3

Not quite. Let the missing angle be \(x\). Since it's isosceles and all of the angles in a triangle need to add up to \(180^\circ\), we can say:\[x+x+105^\circ = 180^\circ\]Now, just solve for \(x\).

Answer 4

No, it's B. You do: 180- 105 = 75. So 75 is the sum of the other two angles which also equal. So just an algebraic intuition here, if each angle is x, we can say: x+x=75 => 2x=75 => x = 75/2 = 37.5

Answer 5

okay im so confuse i got different answers from everyone that i dont knoe who to believe

Answer 6

They're all the same answer, different methods.

Answer 7

just believe in the math! </cheesy>
