The measures of the angles of a triangle are shown in the figure below. Solve for x.
(4x-5)°
(3x-3)

Answer: x = 88/7 or 12.5714285714
Step-by-step explanation:
All sides of a triangle add up to 180.
Therefore...
90 + (4x + 5) + (3x - 3) = 180
(4x + 5) + (3x - 3) = 90
4x + 5 + 3x - 3 = 90
7x + 2 = 90
7x = 88
x = 88/7 or 12.5714285714
Answer:
x = 14
Step-by-step explanation:
Interior angles of a triangle sum to 180°.
Therefore, the find the value of x, sum the given angles, equal them to 180 and solve for x:
[tex]\begin{aligned}\implies (4x-5)+(3x-3)+90&=180\\ 4x-5+3x-3+90&=180\\ 4x+3x-5-3+90&=180\\ 7x+82&=180\\ 7x+82-82&=180-82\\ 7x&=98\\\dfrac{ 7x}{7}&=\dfrac{98}{7}\\x&=14\end{aligned}[/tex]
