Answer:
Step-by-step explanation:
If we are given angles B and C, then all we have to do is add them together and then subtract that from 180 since all the angles of a triangle have to add up to equal 180.
62 + 48 = 110
180 - 110 = 70
Angle A = 70°
Answer:
should be 27
Step-by-step explanation:
60% of 180 is 108
25% of 108 is 27
Answer:
20
Step-by-step explanation:
y^2+4y-1=(-7)^2+4(-7)-1=(-7)(-7)-28-1=49-28-1=21-1=20
Answer: 
Step-by-step explanation:
Point slope form: 
, where n=slope , (a,b) is the point through which line passes.
If slope of the line = m and line passes through
