Answer:
B = 35° , a = 55.256, b = 32.401
Step-by-step explanation:
To get B we know that triangle has sum of ° 180, for solving a and b we will use law of sine where a/sinA = b/sinB = c/sinC
Answer:15
Step-by-step explanation:
If 85% pass then 15% failed and 15% of 1,200 is 180 so 180 people failed.
Using PEMDAS, we know that we must solve what’s in the perentheses first so: 25/5 + 7 - (4x3) = 25/5 + 7-12. Next, we simplify 25/5 because that is division so now it is 5+7-12. Now you add 7 to 5 to get 12 and then subtract 12 so your answer is now zero.
