How do you do this help​

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.

MZYX=pi/3 radians. Covert this radian measure to its equivalent degree measure.
vitfil [10]

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.

Here's a graph of a linear function. Write the equation that describes that function. Express it in slope intercept form
m_a_m_a [10]

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
