Step-by-step explanation:
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°
The answer is a.2
This is because when using the Pythagorean theorem we have A squared plus B squared equals C squared. And C squared would be the hypotenuse so, A would be 4 and C would be the square root of 20. After doing this solving using the order of operations you should finally get B squared equals 4. Thus causing B squared to be equal to 2.
