Step-by-step explanation:
Answer:
(a) 17°
(b) 78°
Step-by-step explanation:
(a) sin A= 0.2896
to calculate for "A" check for sin inverse of 0.2896
A= sin^-1(0.2896) = 16.83
to the nearest degree A= 17°
(b) tan A = 4.7046
A= tan^-1(4.7046)
A = 77.99
to the nearest degree A = 78°
Answer:
A 7.81
Step-by-step explanation:
Use the distance formula to find the distance between coordinates.
![d = \sqrt{(2--4)^2 + (5-0)^2} \\d = \sqrt{(2+4)^2 + (5)^2} \\d = \sqrt{(6)^2 + (5)^2} \\d = \sqrt{36 + 25} \\d = \sqrt{61} \\d=7.81](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%282--4%29%5E2%20%2B%20%285-0%29%5E2%7D%20%5C%5Cd%20%3D%20%5Csqrt%7B%282%2B4%29%5E2%20%2B%20%285%29%5E2%7D%20%5C%5Cd%20%3D%20%5Csqrt%7B%286%29%5E2%20%2B%20%285%29%5E2%7D%20%5C%5Cd%20%3D%20%5Csqrt%7B36%20%2B%2025%7D%20%5C%5Cd%20%3D%20%5Csqrt%7B61%7D%20%5C%5Cd%3D7.81)
