1. 2*0.8 = 1.6 PQ = 1.6
2. arctan(14/12) = 49.4 degrees
3. 15 * cos(70) = 5.1 feet
4. x = 30 * cos(40) = 22.9813 = 23.0 miles
y = 30 *sin(40) = 19.2836 = 19.3 miles
The correct answer is the middle option
Step-by-step explanation:
Three times the sum of a number and 4 is the same as 18 less than a number.
Solution,
Let the number be x, then
3(x+4)=x-18
3x+12=x-18
3x-x=-18-12
2x=-30
x=-30/2
x=-15
