Answer:
109
Step-by-step explanation:
alternate exterior angles
Answer: 5
Because 986443 and in the middle there is 6 and 4. So you work out (6+4) divide by 2 which is 5.
<u>ANSWER</u>:
(y + 5) + y = 6 (second option)
<u>EXPLANATION:
</u>From the given system of equation. we substitute the second equation x = y + 5 in the first equation x + y = 6 to get
x + y = 6
>> (y + 5) + y = 6
Answer:
k = 10
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
115° is an exterior angle of the triangle, thus
4k + 5 + 6k + 10 = 115, that is
10k + 15 = 115 ( subtract 15 from both sides )
10k = 100 ( divide both sides by 10 )
k = 10
