Step-by-step explanation:
∠A + ∠B + ∠C = 180°
Here the value of ∠B and C is given below...we need to find the value of ∠A ....
a + 120° + 40° = 180°
a + 160° = 180°
a = 160° - 180°
a = 20°

Answer:
6 centimeters and 4 centimeters
Step-by-step explanation:
According to the Triangle Inequality, the sum of the lengths of any two sides of a triangle has to be greater than the third side. The answer choices that satisfy the Triangle Inequality is 6 centimeters and 4 centimeters.
2x-5=15
2x=20
x=10
the answer is B
The solution of the inequality is x ≥ 1.
Solution:
Given inequality:

To find the solution of the inequality:

Subtract 8 from both sides.


Divide by 3 on both sides.

On simplifying this, we get

The solution of the inequality is x ≥ 1.
