The cosine of A is (adjacent side)/(hypotenuse) = 55/73. Do the division, then find the angle whose cosine is that number. The whole thing takes maybe 6 or 7 seconds with your calculator. It's choice-B.
Answer:
A
Step-by-step explanation:
Add 3x^2 and 5x^2 now it = 8x^2
Add -8x and -4x = -12x
look at your answer choices the only one that has 8x^2-12x is A
1/2x + 1 = 2/3x
1/2x - 2/3x = -1
-x/6 = -1
x = 6
Hope this helps!
Student programs = 12,000 x 0.5 = 6000
teacher programs = 12000 x 0.23 = 2760
school supplies = 12000 x 0.17 = 2040
technologies = 12000 x 0.10 = 1200
1. 6000 - 2040 = 3960 this is TRUE
2. 6000 - 1200 = 4800 this is FALSE
3. 6000 + 2760 = 8760 ( approximately 8800) this is TRUE
4. teacher programs = 2760 this is FALSE
5. FASLE
1 and 3 are correct answers
