The answer to the question above is x=-4.5
Answer:
Step-by-step explanation:
for nr. 1
sum of angles in a triangle=180
x=180-(81+84)=15
acute triangle
for nr.2
x=180-(24+36)=120
obtuse triangle
247- 538 = -291
If you line them up in that order 247 you'll have to borrow. Your answer would be -291
-538
The only way to not get -291 is to flip the two numbers.
-4 is what you put on both sides Bc it’s half of b
The interior of a triangle = 180°
So 180° - 85° -50° = 45°
c. 45 degrees
