In the triangle below,∠1= 35° and ∠6 = 70°. WHat is the measurement of ∠4? ∠4= ?°

julia-pushkina [17]

Answer:

145°

Step-by-step explanation:

< 6 + <2 = 180° {being linear pair }

70° + < 2 = 180°

< 2 = 180° - 70°

< 2 = 110°

Now

< 4 = < 1 + < 2 (exterior angle of a triangle is equal to the sum of two opposite interior angles)

<4 = 35° + 110°

= 145°

Hope it will help :)

Solve 7x + 1 < 4(x - 2). {x | x < 3} {x | x > 3} {x | x > -3} {x | x < -3}

Luda [366]

Hello there!

Answer:

$\boxed{D. x$

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, you expand.

4(x-2)=4x-8

7x+1<4x-8

Subtract by 1 both sides of an equation.

7x+1-1<4x-8-1

Add/Subtract numbers from left/right.

8+1=9

7x<4x-9

Then, you subtract by 4x both sides of an equation.

7x-4x<4x-9-4x

Simplify equation.

3x<-9

Divide by 3 both sides of an equation.

3x/3<-9/3

Divide numbers from left/right.

-9/3=-3

x<-3 is the final answer.

Hope this helps!

Thanks!

Have a nice day! :)
