The three inside angles (A,B and C) of a right angled triangle are in the ratio 7:18:11

Anastasy [175]

This is overdetermined. Without looking at the ratio (except for the order of the sides) the actute angles in a right triangle are complementary so the answer must be:

Answer: A=35°, C=90°, B=55°

We can do it the way they like.

7+18+11 =36

so to get 180 degrees we need to scale the ratio elements by a factor of 5.

7:18:11=35:90:55

A is the smallest. We see C is indeed a right angle and B is complementary to A.

Simplify the polynomial (4n² + 3n – 5) − (2n² + 3n<br> -<br> + 6)

Veseljchak [2.6K]

Answer:

2n² + 1

Step-by-step explanation:

Given polynomial:

(4n² + 3n – 5) − (2n² + 3n - 6)

Solution:

Removing parentheses,we obtain

$4n {}^{2} + 3n - 5 - 2n {}^{2} - 3n + 6$

Combine like terms:

$4n { }^{2} - 2n {}^{2} + 3n - 3n - 5 + 6$
$2n { }^{2} + 0 + 1$
$\boxed{2n {}^{2} + 1}$

Done!
