360 - 120 - 150 = 90
Interior Angle 1 = 180 - 120 = 60°
Interior Angle 2 = 180 - 150 = 30°
Interior Angle 3 = 180 - 90 = 90°
Answer: 102°
Step-by-step explanation:
First and foremost, we should note that an isosceles triangle has two sides that are equal and that the sum of angles in a triangle equals to 180°.
Since we are told that the isosceles triangle has base angles that each measure 39°, the third angle will be:
t + 39° + 39° = 180°
t + 78° = 180°
t = 180° - 78°
t = 102°
The third angle is 102°.
Step-by-step explanation:
f(x) = 4x + 5, g(x) = 9x − 4
(f-g)(x) = f(x) -g(x)
=4x+5-9x+4
=-5x+9
=9-5x
It is zero
the answer is 5.3 x 10^0
because 10^1 would force you to move the decimal place to make it 53
I hope this helps!
