Just do b*h/2 for all the triangles.
Answer:
2/5
Step-by-step explanation:
For the denominator you are looking for the total number of options, and in this case it is 10. Then for the numerator you are looking for what the question is asking for, in this case, it is looking for letters n to q. n, o, p and q are what you are looking for. With this information you will get 4/10 and simplified, 2/5
Answer:
12°
Step-by-step explanation:
a right triangle implies there is an angle that is 90°
another angle is 78°
the third angle is 180 - (90 + 78) = 180 - 168 = 12°
Answer:
6
Step-by-step explanation:
base + 2(legs) = 56 (2 legs are the same because it's isosceles)
x + 2(5x - 5) = 56
x + 10x - 10 = 56
11x -10 = 56
11x = 66
x = 6
Answer: No solution
Step-by-step explanation: -12x-14=-62-12x
You would have to simplify the -12x but you can't so this would be a no solution.
