Answer:
y = 15°
∠A = 78°
∠B = 68°
∠BAC = 34°
Step-by-step explanation:
∠BAC = 180° - 146° = 34°
the sum of the interior angles of any triangle is 180°
5y + 3 + 4y + 8 + 34° = 180°
combine like terms:
9y + 45° = 180°
subtract 45° from each side of the equation:
9y = 135°
divide both sides by 9:
y = 15°
∠A = 5(15) + 3 = 78°
∠B = 4(15) + 8 = 68°
Answer:
first add the numbers that have the same variable s x7+8x=15x
then the numbers first add and then you subtract
1+7=8
3-8= -5
15x-5
5.8 = 58/10 = 29/5 ;
1.2 = 12/10 = 6/5;
(29/5) ÷ (6/5) = (29/5) × (5/6) = 29/6 = 4.83;
The correct answer os D.
This answer is A. 19.5/3.25=6
Answer: A)10 B)14 C) 12 D)10
Step-by-step explanation:
You would cross multiply and divide! So for part A you would multiply 2x55 which equals 110 then divide that by 11 and get 10. You then repeat that for each part!
