If the two acute angles of a right triangle have measures (2x-11) and (x+26) , then what is the value of X

Alinara [238K]

ANSWER

$x = 25 \degree$

EXPLANATION

The sum of the interior angles of a triangle is
$180 \degree.$

In a right angle triangle, one of the angles is already
$90 \degree.$

Therefore the remaining two acute angle will add up to
$90 \degree.$

This implies that,

$(2x - 11) + (x + 26) = 90 \degree$

We group like terms to get,

$2x + x + 26 - 11 = 90$

This gives us,

$3x + 15 = 90$

This gives,

$3x = 90 - 15$

$3x = 75$

We divide both sides of the equation by 3 to obtain,

$x = 25 \degree$

sergij07 [2.7K]

Answer:

In the third round, total family members contacted is 8.

Step-by-step explanation:

Let us assume that Mrs Rayne contacts two members in her family say A and B

or, Total new members contacted in First Round = A and B (2 members)

Now, in second Round, A contacts two members say H and G

and B contacts L and M

So, Total new members contacted in second round = H, G ,L and M (4)
