kozerog [31]

Answer:

x = 20

Step-by-step explanation:

The triangle is isosceles ( 2 congruent sides )

Hence the base angles are congruent, thus

3x = 60 ( divide both sides by 3 )

x = 20

marissa [1.9K]

Answer:

tank 1 : 19 gallons

tank 2 : 42 gallons

Step-by-step explanation:

tank 1 : x

tank 2 : 2x+4 ( 4 more than twice the other )

x + ( 2x + 4 ) = 61

3x + 4 = 61 [ add x + 2x = 3x ]

3x = 57 [ subtract 4 on both sides ]

x = 19 [divide 3 on both sides ]

tank 1 : 19 gallons

tank 2 : 42 gallons

Answer:

x = 20

Step-by-step explanation:

If two lines are cut by a transversal and the corresponding angles are congruent, the lines are parallel.

$\rm \longrightarrow \angle 2 = \angle 5 \\ \\ \rm \longrightarrow 3x - 20 = x + 20 \\ \\ \rm Add \ 20 \ both \ sides: \\ \rm \longrightarrow 3x - 20 + 20 = x + 20 + 20 \\ \\ \rm \longrightarrow 3x = x + 40 \\ \\ \rm Substrate \ x \ from \ both \ sides: \\ \rm \longrightarrow 3x - x = x - x + 40 \\ \\ \rm \longrightarrow 2x = 40 \\ \\ \rm Divide \ both \ sides \ by \ 2: \\ \rm \longrightarrow \frac{ \cancel{2}x }{ \cancel{2}} = \dfrac{40}{2} \\ \\ \rm \longrightarrow x = 20$
