Answer:
<A = 18.6 Degree
<B =74.4 Degree
<C = 87 Degree
Step-by-step explanation:
Sum of all the angles of triangle is 180
as given ,
<A = ?
<B = 4<A
<C = 5 <A - 6
As per rule ,
<A + <B +<C = 180
<A + 4 <A + 5<A - 6 = 180
10 <A - 6 = 180
10 <A = 180 + 6
<A = 186 / 10
<A = 18.6 Degree
Hence ,
< B = 4 X (18.6)
< B = 74.4 Degree
and
<C = 5 (18.6) - 6
<C = 87 Degree
PROOF
<A + <B + <C = 180
18.6 + 74.4 + 87 = 180
180 = 180
Answer:
14
Step-by-step explanation:
Answer:
k = -10/9
Step-by-step explanation:
Take the antilog:
36(3k +7) = 132
3k +7 = 3 2/3 . . . . divide by 36
3k = -3 1/3 . . . . . . subtract 7
k = -1 1/9 . . . . . . . divide by 3
