The sum of the angles of a triangle is 180 degrees. If one of the acute angles of a right triangle is 52 degrees, what is the me

Arada [10]

Answer:

An equation is $x+52\°+90\°=180\°$

Step-by-step explanation:

Let $x$ be the measure of the unknown acute angle.

According to angle sum property of a triangle, sum of all the angles of a triangle is equal to 180°.

One of the acute angles of a right triangle is equal to 52°.

Also, the triangle is a right angled triangle, one of the angle must be equal to 90°.

$x+52\°+90\°=180\°\\x+142\°=180\°\\x=38\°$

So, an equation is $x+52\°+90\°=180\°$

A ceiling 6 feet by 7 feet can be painted for $52. find the cost of painting a ceiling 18 feet by 21 feet, all things being equa

kykrilka [37]

6 feet * 7 feet = 42 feet²

18 feet * 21 feet = 378 feet²

42 feet² was painted for $52

1 feet² will be painted for $52/42

378 feet² will then be painted for: ($52/42) * 378

= $468

Hence 18 feet by 21 feet will be painted for $468

Hope this helps.
