Answer:
Can’t rlly see 1-4
Step-by-step explanation:
5:a=12,b=5
a^2+b^2=c^2
144+25=169
c=13
6: a=8, c=10
64+b=100
b=6
7: a=15,c=17
b=8
8:b=40,c=50
a=30
9:b=2,c=4
a=2 root 3

Answer:
Altogether James walked
miles.
Step-by-step explanation:
The question involves mixed fractions. Mixed fractions are first converted into proper fractions and then any operation can be performed on them.
Given
Distance of first walk =
of a mile
Distance of second walk = 5/7
In order to find how much he walked altogether, we have to find the sum of both fractions.

Hence,
Altogether James walked
miles.
87 ° to radians in terms of pi =
=> 87 ×

=>

The principle behind this conversion is that we know that π radians is equal to 180 thus we are simply 'rationalizing' to include π in the answer.
