x=4.75
6×4.75=28.5
15×4.75-12=59.25
19×4.75+2=92.25
28.5+59.25+92.25=180
m<MNI= 92.25
I think this is right. I hope that it was helpful:)
BD = 46
Explanation:
BC = CD and AC is used for both triangles so AD MUST = AB.
If AB = 23, then AD = 23.
BD = AB + AB
BD = 23 + 23
BD = 46
Answer: the answer is D
Step-by-step explanation: may i please have brainliest.
Answer:
f(x) + g(x) = (-2x + 8)+ 3x
f(x) + g(x) = -2x + 8 + 3x Combine like terms.
f(x) + g(x) = x + 8
f(x) + g(x) = (f+g)(x) = x + 8
(f + g)(-1) = -1 + 8
(f + g)(-1) = 7
Step-by-step explanation:
6x + ( 3x - 9) = 90°( being complementary angles )
6x+3x -9 = 90°
9x = 90° + 9
x = 99 / 9
x = 11
