Answer:
4 3/4
Step-by-step explanation:
= (8 - 3) + (1/4 - 1/2)
= 5 + 1/4 - (1 x 2 over 2 x 2)
= 5 + 1/4 - 2/4
= 5 and (1/2 over 4)
= 5 + -1/4
= 4 3/4
Answer:
option 3
Step-by-step explanation:
49/9 + 17/5 = 398/45 or 8 38/45
Answer:
m∠A = 58°
Step-by-step explanation:
In ΔABC,
m∠BAC = (x + 63)°
m∠ABC = (x + 96)° [Vertically opposite angles]
m∠ACB = (180° - 149°)
= 31°
By triangle sum theorem,
m∠ABC + m∠ACB + m∠BAC = 180°
(x + 96) + 31 + (x + 63) = 180°
2x + 190 = 180
2x = -10
x = -5
Therefore, measure angle A = (x + 63)
= -5 + 63
= 58°
