Answer:
A=81
Step-by-step explanation:
the first bullet is harder, but stuff you'll need to know eventually. The second bullet is SUPER simple.
a²+b²=c².
- One way you can do it; we know that c²=225, so find the square root of that. (it's 15). we also know that either a² or b² is 144. so now we square root that. (its 12). so we know that 15²-12²=b². or that 15²-12²=b². it doesn't matter if it's a or b. pick whichever one you want. plug one if the equations in, and you'll get 81.
- Second way you can do it, which is easier. 225-144=81. this is the same as above, but skipping steps. good for simple math, but later on with harder math it might make things confusing.

Answer:
60°
Step-by-step explanation:
Angles can be converted from radians to degrees by multiplying by 180/π.
π/3 * 180°/π = 180°π /3π = 180/3 = 60°
60° is the measure of ZYX in degrees.
Answer:
y = (1/2)x + 3
Step-by-step explanation:
Slope intercept form is
y = mx + b
m is the slope
b is the y-intercept
The line rises 1 in y for every run of 2 in x
m = slope = rise/run = 1/2
b, The y-intercept is 3
The equation is
y = (1/2)x + 3
Try dividing 600 by 5..
600 / 5 = 120
then times 120 by 9 to get the whole number = 1080
