The nearest whole number for 9.391 divided by 2.8 is 9 and 3, because 9.391/2.8=3.3539 and 9/3=3 which is closer to the initial answer so the nearest number whole number will be 9/3.
Quadrant 2 is where it would b
Solve for y in the first equation.
Answer:
A = 21 degrees
Step-by-step explanation:
Here in this question, we are told to calculate the value of angle A.
When two angles are tagged complementary, what this means is that the addition of both angles gives a total of 90 degrees.
Hence;
A + B = 90
This means that;
(x-21) + (2x -15) = 90
x + 2x -21-15 = 90
3x -36 = 90
3x = 90+ 36
3x = 126
x = 126/3
x = 42
But we are told to calculate the measure of A
A = x -21
A = 42-21
A = 21 degrees
