Question

In the diagram, what is the measure of angle 1 to the nearest degree?

Answer 1

Answer:

$m$

Step-by-step explanation:

Step 1

Find the value of x

we know that

$(7x+4)\°=88\°$ ----> by vertical angles

Solve for x

$7x=88-4$

$x=84/7=12\°$

Step 2

Find the measure of angle 1

we know that

$m$ ------> by supplementary angles

Substitute the value of x and solve for m<1

$m$

$m$

$m$

Answer 2

7x+4=88
7x=84
x=12
7x-12=7*(12)-2=82
angle 1=180-82=98
