Answer:
d=90 e=27 f=153
Step-by-step explanation:
since 90 is one half of 180 if d was any bigger or smaller the the information given would be incorrect.
e is 27 since vertical angles
f is 157 since a line is equal to 180 and since e is 27 you subtract 27 from 180
Answer:
(7,9)
Step-by-step explanation:
7x - 8y = -23
7x - 7y = -14
Solve the equation for 7x
7x - 8y = -23
7x = -14 + 7y
Substitute the given value of 7x into the equation 7x - 8y = -23
-14 + 7y - 8y = -23
solve the equation for y
y = 9
substitute the given value of y into the equation 7x = -14 + 7y
7x = -14 + 7(9)
solve the equation for x
x = 7
<u>(7,9)</u>
