Answer:
For question 1 it's B
For question 2 it's C
Step-by-step explanation:
For question 1, you have to apply the "Triangle Inequality Theorem"
A+B > C
B+C > A
A+C > B
Let's say that A=22, B=17, C= 14
22+17 > 14 True
17+14 > 22 True
22+14 > 17 True
Therefore, the answer is B
For question 2, you apply the rule of the sum of the triangles which is 180°
70+70+? = 180
140+? = 180
? = 40
Therefore, it's C
