Answer:
y=0
Step-by-step explanation:
Rewrite Evaluate Powers:
3
Calculate:

Solve using substitution:

Solve the equation for t:
t=-3
t=1
Substitute back to t=3^y
3^y=-3
3^y=1
y∉R

y=0
Here's the solution,
The given triangle is an <u>equilateral triangle</u>, because it's all angles measure 60° each
now,
Area of an equilateral triangle :
=》

where,
=》

=》

=》

or
=》

Answer:
57
Step-by-step explanation:
180-123=57
that line the angle is on is a straight line and a straight line is 180 degrees
we know that

so
by proportion
Find how many millimeters are in
meters

therefore
<u>the answer is</u>

We have to use Pythagorean theorem that says :

The missing length of the triangle is : 36 feet
