Answer: it can have at most one right angle but at most, 2 acute angles

Step-by-step explanation:

A triangle is a shape bounded by 3 sides and it has three angles.

The sum of the angles is 180 degrees

A right angle is 90 degrees. So a tight angled triangle has one of the angles equal to 90 degrees.

An acute angle is an angle lesser than 90 degrees.

An obtuse angle is an angle greater than 90 degrees but lesser than 180 degrees. Assuming we have a right angle triangle.

So a triangle can have at most one right angle while a triangle can have more than one acute angle. For example, a right angled triangle has two acute angles. So also, a triangle containing an obtuse angle has two acute angles

Solving exponential equations

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle 3^{6x + 18} < 27^{3x}$

Step 2: Solve for x

Rewrite: $\displaystyle 3^{6x + 18} < 3^{3(3x)}$
Set: $\displaystyle 6x + 18 < 3(3x)$
Factor: $\displaystyle 3(2x + 6) < 3(3x)$
[Division Property of Equality] Divide 3 on both sides: $\displaystyle 2x + 6 < 3x$
[Subtraction Property of Equality] Subtract 3x on both sides: $\displaystyle -x + 6 < 0$
[Subtraction Property of Equality] Subtract 6 on both sides: $\displaystyle -x < -6$
[Division Property of Equality] Divide -1 on both sides: $\displaystyle x > 6$
