Hope this helps.
Answer:
Acute
Step-by-step explanation:
20:30 so it becomes 2:3 as a fraction it would be 2/3. a fraction is basically a ratio.
To solve:
T/6-14=-20
+14 +14 ISOLATE T/6: inverse operations on -14. (Add)
-----------------
T/6= 6
*6 *6 ISOLATE T: Inverse operations on 6. (Multiply)
-------------
T=36
Answer:
Note :
The perimeter is : AB + BC + CA
AB =√((XB - XA)² + (YB - YA)²) = √((16-2)²+(2-8)²) = √(12²+6²) = √(144+36)=√180
AB = √(36×5) = 6√5 units
same method for : BC ; CA ..........
