Two supplementary angles are in the ratio of 31:5 find angles

ad-work [718]

Answer:

The angles are 155° and 25°.

Step-by-step explanation:

Given:

Two supplementary angles are in the ratio of 31:5.

Now, to find the angles.

The sum of two supplementary angles = 180°

Let the ratio of the angles be $31x\ and\ 5x$ .

So, according to question:

$31x+5x=180\°$

$36x=180\°$

Dividing both sides by 36 we get:

$x=5$

So, $31x=31\times 5=155\°.$

And, $5x=5\times 5=25\°.$

Therefore, the angles are 155° and 25°.

If f(x)=2x+7 and g(x)=11x-4, find (f+g)x.

klemol [59]

Answer:

(f+g)(x) = 13x + 3

Step-by-step explanation:

Rewrite f(x)=2x+7 and g(x)=11x-4 in columns, as follows:

f(x)=2x+7

+g(x)=11x-4

----------------

Now add each column separately.

f(x)+g(x) = (f+g)(x) ("the sum of functions f and g")

2x + 11x = 13x, and, finally, 7-4 = 3.

Therefore,

f(x)=2x+7

+g(x)=11x-4

----------------

(f+g)(x) = 13x + 3
