The angles of a triangle add up to 180 degrees
65 + 3x - 10 + 2x = 180
5x + 55 = 180
5x = 180 - 55
5x = 125
x = 125/5
x = 25 <====
m < B = 3x - 10 = 3(25) - 10 = 75 - 10 = 65 <== B is 65 degrees
m < C = 2x......= 2(25) = 50 <== C is 50
Keep adding by the same value everytime so start with 10,000 then add 20,000 etc
Answer:
-41
Step-by-step explanation:
The change is -2
(-2*20)-1 = -41
Idk but it can't be 10 or 9.7 bc a triangle's hypotenuse is always longer than its legs
