a) Here, sum of two non-adjacent angles: 52 + 25 = 77
Now, ∠3 = 180 - 77 [ sum of all angles in a triangle is 180 ]
so, ∠3 = 103
Now, ∠3 + ∠4 = 180 [ Supplementary angles ]
So, ∠4 = 180 - ∠3
∠4 = 180 - 103 = 77
∠4 = 77 [ which is sum of two non-adjacent angles ]
....Hence proved.
b) m∠4 = 77
[ Solved in previous section ]
Hope this helps!
Umm , what is this for? do you need help on anything or? lol
Answer:
77/84
Step-by-step explanation:
84 ÷ 12 = 7

Answer: 109
Step-by-step explanation: Substitute in 4 for m and 5 for n in the equation:
(4)^3 + 9(5)
(4*4*4) +45
(16*4) +45
64+45 =109
