PLEASE HELP!!! Find each measure. m<1, m<2, m<3
Mashcka [7]

Number 1: To find number 1 use hypotenuse theory. 180-(69+31) is the equation. After you solve it you get m<1 as 80.

Number 2: Since you already found m<1 find the other angle across from it.

Equation is: 180-80, which equals to 100.

Then once you have two angles use the theory again: 180-(100+45)=35.

Therefore m<2=35.

Number 3: Still using m<1, 180-100=80. Now you have to angles you get the equation:

180-(80+47), which equals to 53. Therefore m<3=53

Answers: m<1=80; m<2=35; m<3=53

x+x+1+x+2=135 or add like terms
3x+3=135
subtract 3 from both sides
3x=132
divide by 3
x=44
firts number=44
