Answer:
1. 69°
2. 97°
3. 145°
4. 150°
5. 128°
6. 74°
Step-by-step explanation:
To find the angle measure of the missing angle, we have to note that the angle measures of a quadrilateral will all equal up to be 360°.
If we know 3 out of the 4 angles and the sum of the angles, we can add up the angles we know then subtract that from 360.
Number 1:
[tex]87+112+92=291[/tex]
[tex]360-291=69[/tex]
Number 2:
[tex]124+71+68=263[/tex]
[tex]360-263=97[/tex]
Number 3:
[tex]95+46+74=215[/tex]
[tex]360-215=145[/tex]
Number 4:
[tex]72+49+89=210[/tex]
[tex]360-210=150[/tex]
Number 5:
[tex]69+65+98=232[/tex]
[tex]360-232=128[/tex]
Number 6:
[tex]77+123+86=286[/tex]
[tex]360-286=74[/tex]
Hope this helped!
