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:
X = 51
Y = 12
Step-by-step explanation:
2 numbers: (Larger) Number 1 is x and Number 2 is y
The equation is x + y = 63
New equation is:
Combine like variables:
Solve:
- 4y + 15 - 15 = 63 - 15
- 4y = 48
Divide 4 from each side:
To find x fill in the variables from the 'x =' equation:
- x = 3y + 15
- x = 3( 12) + 15
- <em><u>x = 51</u></em>
