4 0

Answer:

-15

Step-by-step explanation:

x-1/2(x+5)=-10

x-1/2x-5/2=-10

2/2x-1/2x-5/2=-10

1/2x-5/2=-10

1/2x=-10+5/2

1/2x=-20/2+5/2

1/2x=-15/2

x=(-15/2)/(1/2)

x=(-15/2)(2/1)

x=-15/1

x=-15

<1 and <2 form a linear pair. The measure of <2 is six more than twice the measure of <1. Find the measure of <2
MrMuchimi

Answer:

122 Degrees

Step-by-step explanation:

Since we are given that angle 1 and 2 make a linear pair:

angle 1 + angle 2 = 180 degrees ----------------------------(1)

We have also been told that angle 2 is 6 more than twice the measure of angle 1

Which means: angle 2 = (2*angle1)  + 6 -------------------(2)

From putting the value of angle 2 in (1) from (2)

<em>angle 1 + 2*angle 1 + 6 = 180</em>

<em>3*angle 1 = 174</em>

angle 1 = 58 degrees -----------------------(3)

From (1) and (3):

<em>angle 2 + 58 = 180</em>

angle 2  = 122 degrees

Therefore, the measure of angle 2 is 122 degrees
