The complement of an angle is three times the measurement of the angle. Find the measurement of the larger angle.

olganol [36]

We know that two complements add up to 90.
Let's call the smaller angle x and the larger y.
3x = y
x + y = 90
We can use simple substitution.
x + 3x = 90
4x = 90
x = 22.5

Then, since we know that 3x=y, we can find the larger angle.
3*22.5 = 67.5

Use inverse operations and properties of equality to isolate the variable m+31=307

otez555 [7]

ANSWER

$m = 276$

EXPLANATION

The given equation is

$m + 31 = 307$

We add the additive inverse of 31 which is -31 to both sides of the equation to get,

$m + 31 + - 31= 307 + - 31$

Simplify;

$m +0= 307 - 31$

$m = 276$

31/6 as a mixed number

liubo4ka [24]

Hello there awesome brainly user!

To convert $\frac{31}{6}$ to a mixed number you have to divide 31/6 which equals 5 R 1 Remember that the remainder is the numerator and the whole number is 5. So, the mixed fraction is $5\frac{1}{6}$

Find three consecutive numbers whose sum is 84

mrs_skeptik [129]

Answer:

27 28 29

Step-by-step explanation:

Let the first be n , and if they are consecutive then the next two numbers are n+1 and n+2.

n+(n+1)+(n+2)=84.

3n+3=84.

⇒3n=81.

⇒n=27.

Hence numbers are n,n+1,n+2→27,28 and 29
