In △ABC
, m∠A=x°
, m∠B=(3x+30)°
, and m∠C=2x°
. What is the measure of ∠B
?

105

Step-by-step explanation:

Angle A, B, and C all add up to 180 degrees. So you combine the equations and get “6x+30=180” so x=25 and then you plug 25 for x into the equation for angle B and you get “75+30” which equals “105”.

because 1.2 isnt half of 6 duh

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
