Answer:
=76
Step-by-step explanation:
24+(−9)(−4)+33−17
=24+36+33−17
=60+33−17
=93−17
=76
Both angles add up to 180.
180-100=80
The missing angle is 80°.
So we find what's called the GCF or greatest common factor
firest we find teh factors and group the like ones
40=2 times 2 times 2 times 5
20=2 times 2 times 5
we see a common set of numbers which is in both which is 2 times 2 times 5=20
biggest number that can go into both 40 and 20=20
