Answer:
12
Step-by-step explanation:
3 divided by 1/4 = 3 x 4 = 12
21.2264 is 21.2 rounded to the nearest tenths; the place after the decimal is there tenths place so in the hundreths place, the number 2 is less than 5 therefore rounding it to 2.
Find the b value by plugging in the slope and known coordinates,
-2=0(4)+b
-2= 0+b
-2=b
You can also tell this without calculating since a slope of 0 will always have the same y value. Therefore if (4,-2) is on the line, the y value of the whole line must be -2.
Final answer: y=0x-2, which is y=-2
(22 x sin(65))/sin(53) =24.96604654 rounded of to nearest tenth = 25
So X = 25
