The other angle would be 118°
The three angles of a triangle must add up to 180°.
Hey there! I'm happy to help!
Here is our equation
3x - 4 (2x - 5) = 15
First, we will sue the distributive property to remove the parentheses. The term outside the parentheses is -4, so that is what we multiply the insides by.
3x-8x+20=15
We combine our like terms (our x-values).
-5x+20=15
We subtract 20 from both sides.
-5x=-5
We divide both sides by -5.
x=1
Have a wonderful day and keep on learning! :D
35% decrease as a multiplier = 1 - 0.35 = 0.65
1900 x 0.65^4 = 802.75

5x³ - 5(3)³
Factor 5
5[ x³ - (3)³]
5 [ (x - 3)(x² + 3x + 9)]
