Answer:
13
Step-by-step explanation:
since the inside of a triangle is equal to 180
180-42-73=65
65/5=13 so 13 should be the answer.
Answer:
3/8
Step-by-step explanation:
-3/2 can change to -12/8
7/4 can change to 14/8
1/8 stays the same
-12/8 + 14/8 = 2/8 + 1/8 = 3/8
Y is less than or equal to -16 i think but I’m not sure
Process:
1. 21+24n= 7
2. 24n= 7 - 21
3. 24n= -14
Answ: n= -7/12
I think the answer is b. cos(pi theta)= -0.6
