Answer:
h=55.4 mm
Step-by-step explanation:
Area of a triangle =
where b is base and h is height
now just plug and chug
227.14 = 8.2h/2
227.14=4.1h
h=227.14/4.1
h=55.4
check answer:
55.4 * 8.2 /2 = 227.14, as proven by my calculator

Answer:</h2>
<h3>
<em>x=45degrees</em></h3>
<h2>
Step-by-step explanation:</h2>
Let the angle to be solved be x
Let the supplement/compliment by y
x+y=90 Complimentary angles add up to 90 degrees.
x+3y=180 Supplementary angles add up to 180 degrees, the other angle is thrice the other compliment.
Evaluating this as a system:
x+y=90 Isolate x:
x=90−y Input into the other equation:
(90−y)+3y=180 Combine like terms, isolate y and its coefficients:
2y=90 Isolate y
y=45 Input into the first equation:
x+45=90 Isolate x:
x=45degrees
