The larger of two supplementary angles is 6 less than 5 times the smaller. Find the measure of the two angles.

zimovet [89]

Answer:

Step-by-step explanation:

Let the two angles be x and y

Then: y = 5x - 6

And x + y = 180° (the of supplementary angle is 180°)

Putting y = 5x - 6

x + 5x - 6 = 180

6x = 180 + 6

6x = 186

x = 186/6

x = 31°

And y = 5x - 6

y = 5(31) - 6

y = 155 - 6

y = 149°

The angles are 31° and 149°

3. [09.04]<br> What are the exact solutions of x2 = 5x + 2? (1 point)

uranmaximum [27]

Answer:

x = $\frac{5±\sqrt{33} }{2}\\$

Step-by-step explanation:

I would subtract 5x and 2 on both sides to get x^2 - 5x - 2 = 0, and using the A = 0, B = -5, and C = -2 to plug it into the quadratic equation which is

$\frac{-b±\sqrt{b^{2} -4ac} }{2a}$

*Ignore the A please I cannot get rid of it.*
