If triangle rst is an acute triangle, then m∠s must be

less than 90°.
equal to 90°.
equal to 100°.
greater than 90° and less than 180°.

m ∠ S must be less than 90°

Therefore; if triangle RST is an acute triangle; then;

∠R , ∠S and ∠T, all are less than 90.

yeah and

step-by-step explanation:

you know what it isnt great cheating

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
