Find the measure of the missing angle. ( me) with work

TO FIND THESE MISSING ANGLES WE USE THE 2n-5(90) formula. n represents the amount of the sides.

Then we add the given angles and subtract it from the value of the shape.

3. The missing angle is 159°

2n-5(90)

2(5)-5(90)

10-5*90=450°

119+89+83=291°

450°-291°=159.

4. The missing angle is 69°

2n-5(90)

2(4)-5(90)

8-5*90=270°

122°+79°=201°

270°-201°=69°

HOPE THIS HELPS!

HAVE A GR8 DAY! ;-)

For question 2 :

1 <

2>

3=

Step-by-step explanation:

Basically those triangle arrow things are called 'greater than signs'

So , you need to say which number is bigger than the other or if they are equal. For example :

3>1

1<7

1=1
