Answer:
60
Step-by-step explanation:
Because 7.7^2 equals 60,
The appropriate SI unit for measuring the height of a person is meters.
In this question, you are only able to cancel out the (x + 5). The others are unable to be cancelled.
To get your answer:
9 times 5 times two= 90
9 times 7.5 times two= 135
5 times 7.5 times two= 75
then add all of them together and you will get the surface area
90+135+75=300
you should have an answer of 300 feet²
The complete question in the attached figure
we know that
m∡4=65°
m∡4=m∡2---------> by internal alternate angles
m∡5=m∡3---------> by internal alternate angles
m∡1=180°-m∡2---------> 180°-65°--------> m∡1=115°
the answer is
m∡1=115°
