Find a of this angle.

Mice21 [21]

In a triangle, the total angle is 180 degrees. A straight line is always 180 degrees. With this in mind, the following can be obtained:

$a + 2x + {57}^{o} = {180}^{o} \\ 5x + a = {180}^{o}$

These are simultaneous equations.

$a + 2x + {57}^{o} = 5x + a \\ 3x = {57}^{o} \\ x = {19}^{o} \\ 5x + a = {180}^{o} \\ 5( {19}^{o} ) + a = {180}^{o} \\ a = {85}^{o}$

Kevin is 3 times as old as Daniel. 4 years ago, Kevin was 5 times as old as Daniel.

rusak2 [61]

Answer:

24

Step-by-step explanation:

4 years ago, Daniel would've been 4 and Kevin would be 20, so Kevin would've been 5 times as old as Daniel. And 8 x 3 = 24. So, Kevin is 24.

Suppose y varies directly with x. If y = -4 when x = 8, what is the equation of direct variation?
