In triangle​ abc, the measure of angle b is 32 degrees more than three times the measure of angle
Yuki888 [10]
Define x:
Let angle a be x.
angle a = x
angle b = 3x + 32
angle c = x + 58

Find x:
Angles in a triangle add up to 180°:
x + 3x + 32 + x + 58 = 180

Combine like terms:
5x + 90 = 180

Take away 90 from both sides:
5x = 90

Divide by 5 on both sides:
x = 18°

Find the angles:
angle a = x = 18°
angle b = 3x + 32 = 3(18) + 32 = 86°
angle c = x + 58 = 18 + 58 = 76°

Answer: The angles are 18°, 86° and 76°.

42x+25y=486, x+y=14<br>show work please help asap!​
ruslelena [56]
Rewrite equations:
x+y=14;42x+25y=486

Step: Solvex+y=14for x:
x+y=14
x+y+−y=14+−y(Add -y to both sides)
x=−y+14

Step: Substitute−y+14forxin42x+25y=486:
42x+25y=486
42(−y+14)+25y=486
−17y+588=486(Simplify both sides of the equation)
−17y+588+−588=486+−588(Add -588 to both sides)
−17y=−102
−17y
−17
=
−102
−17
(Divide both sides by -17)
y=6

Step: Substitute6foryinx=−y+14:
x=−y+14
x=−6+14
x=8(Simplify both sides of the equation)
