For this case we have the following inequality:
We add similar terms on the left side of the inequality:
We add 3 to both sides of the inequality:
We multiply by 2 on both sides:
We divide between 3 on both sides:
The solutions are given by all values of x greater than
Answer:
Answer:
Both angles B and C are equal to 40°
Step-by-step explanation:
The diagram tells you that the triangle is an isosceles triangle. From this we know that angles B and C will be equal to each other. To find what the angle measures are, we are going to set the two given expressions equal to each other, solve for x, and the plug x back in to get the two angle measures.
Now we are going to plug x back into each expression to solve for angles B and C.
Angle B
⇒
Angle C
⇒
Both angles B and C are equal to 40°
