Answer:
A or 53 squared
Step-by-step explanation:
Answer:
supplementary angles
Step-by-step explanation:
they are on the same line, so they sum up to 180°
Step-by-step explanation:
I believe the answer is 80 cuz it's in the middle
To solve for P(QIR) we use the formula:
P(QIR)=[P(Q∩R)]/P(R)
But from the diagram:
P(Q∩R)=3/22
P(R)=7/22
hence
P(QIR)=3/22÷7/22=3/7
The area model you can use is D , cs 70 +3 & 30+9
