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:
should be B
Step-by-step explanation:
Consecutive integers = in this situation double-digit whole numbers
So as there are 3 of them let's say 2 are 11 because that would be the highest consecutive number so 11+11= 22 and 48-22=26 so the three have the ages of 11,11,26 and the oldest would be 26 ;)
A perfect cube is a natural number in the form

therefore

and also you can define it as any natural number who's third root is also a natural number for examble
![\sqrt[3]{1000} = 10](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B1000%7D%20%20%3D%2010)
so you can say that the tenth perfect cube is 1000
Answer:
The fourth term in the sequence is equal to the third term plus the common difference, or 16+3=19- last choice
