a + b ≥ 30, b ≥ a + 10, the system of inequalities could represent the values of a and b
option A
<u>Step-by-step explanation:</u>
Here we have , The sum of two positive integers, a and b, is at least 30. The difference of the two integers is at least 10. If b is the greater integer, We need to find which system of inequalities could represent the values of a and b . Let's find out:
Let two numbers be a and b where b>a . Now ,
- The sum of two positive integers, a and b, is at least 30
According to the given statement we have following inequality :
⇒ 
- The difference of the two integers is at least 10
According to the given statement we have following inequality :
⇒ 
⇒ 
⇒ 
Therefore , Correct option is A) a + b ≥ 30, b ≥ a + 10
You need to find the area of one of those bigger triangles, and one of those smaller triangles. Then multiply each area by 6 (because there are 6 sides of the big triangles, and the 6 small triangles make up the other side) and add them together. The area of a triangle is 1/2 times base times height equals area.... Equation: 1/2 (b * h) = A
Answer: 10
<u>Step-by-step explanation:</u>
First, find m∠C by using the Triangle Sum Theorem:
∠A + ∠B + ∠C = 180°
110 + 43 + ∠C = 180°
153 + ∠C = 180°
∠C = 27°
Next, Use the Law of Sines to solve for c:
