An angle is 6 more than five times its supplement. Find the measure of the largest angle.
Julli [10]
Supplementary angles add up to 180°


Angle y is the large angle: y= 5x+6

180= x+y
180= (5x+6) + x
180=6x+6
174=6x
x=29

180= y+29
y=151°

For the following system, use the second equation to make a substitution for y in the first equation. 3x + y = 1 y + 4 = 5x What
Debora [2.8K]

Answer:

The answer is A.

Step-by-step explanation:

So we have the two equations:

3x+y=1\\y+4=5x

To make a substitution of the second equation into the first equation, we need to isolate the <em>y </em>variable in the second equation. Thus:

y+4=5x\\y=5x-4

Now, we can substitute this into the first equation. Therefore:

3x+y=1\\3x+(5x-4)=1\\3x+5x-4=1

HACTEHA [7]

Answer:

17.9°

Step-by-step explanation:

From trigonometry:

Opposite = 14

Adjacent = x

theta = 38°

hence;

tan theta = opposite/ adjacent

tan38° = 14/x

x = 14/tan38°

x = 17.9°
