Answer:
B.6
Step-by-step explanation:
When we add and subtract, we do it from left to right
13+ (-12) - (-5)
13+-12
13-12 = 1
1 - -5
A negative negative is a positive
1 +5
6
Basically you do fractions side by side. so, 6/3=15/h and then cross multiply to get your answer so that would give you 3h=80, then divide 80÷3
Its 75 because you at the 2 variables and then subtract them by 180 so 180-105=75
Answer:
Step-by-step explanation:
take angle B as reference angle
using cosec rule
cosec B=hypotenuse/opposite
cosec B=13/12
cosec B=1.08
B=cosec 67
B=67 degree
for ratio,
cosec B=13/12
