Answer:
80
Step-by-step explanation:
18^2 + 80^2 = 82
324 + 160 = c^2
Answer:
= 
= 
Step-by-step explanation:
triangle ADE and triangle ABC are similar
therefore, the ratio of their corresponding sides are equal
The total amount of degrees in a triangle is 180. All three angles should add up to 180˚
We know that 40+60 = 100
The next step is to do 180-100 to get the other angle.
180-100 = 80
So the measure of the third angle is 80˚
Hope this helps!
(Also if you want to do this in one equation, you would do 40+60+x = 180
40+60+x = 180
100+x = 180 (combine like terms)
x = 80 (Subtract 100 from both sides)
