Step-by-step explanation:
Answer:
a=45 b=65
Step-by-step explanation:
You know that all the angle measures of a triangle add to 180. So the equation would be angle a + angle b + 70 = 180. Subsitute and simplify and you get 16x -2 + 70 = 180. Subtract 70 from 180 to get 16x -2=110 add 2 to get 16x =110. Divide each side by 16 to gte x=7. Subsitute x = 7 into the equations for angle a and angle b to get the answers above
Answer:
exact form: 1/2
decimal form: 0.5
Step-by-step explanation:
4x-12=32-7x
4x+7x=32+12
11x=44
x=4
The 4th one goes with the 1st box
The 2nd one goes with the 2nd box
The last one goes with the 3rd box
