Answer:
m<A = 30degrees
m<B = 70degrees
Step-by-step explanation:
Find the diagram attached
From the diagram;
m<A + 150 = 180
m<A = 180 - 150
m<A = 30degrees
Also since the sum of angles in a triangle is 180degrees, hence;
m<B+m<A + 80 = 180
m<B+30+80 = 180
m<B+110 = 180
m<B = 180 - 110
m<B = 70degrees
Answer:
Two distinct real solutions.
Step-by-step explanation:
Given the equation in the form , you need to find the Discriminant with this formula:
For the equation you can identify that:
Then, substituting these values into the formula, you get that the Discriminant is:
Since , then
has two distinct real solutions.
