Answer:
Step-by-step explanation:
Pythagorean Theorem
c^2 = a^2 + b^2
a = 20
b = 15
c = ?
c^2 = 20^2 + 15^2
c^2 = 400 + 225
c^2 = 625 Take the square root of both sides.
√c^2 = √625
c = 25
The third side is 25 cm long.
Answer:
x=28
Step-by-step explanation:
So a triangle is 180 degrees in total then you would subtract 40 from 180 because the top angle and leaving you with 140 then divide by 5 because the bottom two getting you 28 then you could just plug in 28 for x on each angle
180-40=140
140/5=28
2(28)=56
56 is angle A
