Answer:
66
Step-by-step explanation:
Replace t with 9 in the equation.
Simplify.
Rounded, it equals 66
The sum of all angles of a triangle is equal to 180°
On a isosceles triangle, the base angles are the same.
We add them together 56° + 56° = 112°
To know X, we subtract 112° from the total
180° - 112° = 68°
X = 68°
OR as an equation
56 + 56 + x = 180
112 + x = 180
x = 180 - 112
x = 68
Answer:
2 < x < 3
Step-by-step explanation:
Inequalities: <em>4x - 4 < 8 ∩ 9x + 5 > 23</em>
Simplify:
4x - 4 < 8 ∩ 9x + 5 > 23
4x < 12 ∩ 9x > 18
<em> x < 3 ∩ x > 2</em>
Combine inequalities: 2 < x < 3
