surface area of the triangular prism = 7×10 + 7.62 × 10 + 2× 0.5 × 3×7 + 3×10 cm²
=> 70 + 76.2 + 21 + 30 cm ²
=> 100 + 97.2 cm²
=> 197.2 cm² <em><u>Ans.</u></em>

Answer:
Step-by-step explanation:
b = 20 °
c = 160° ( b/c 180-20 = 160 ) :)
When finding the midpoint, this would signify that we would find the point in the (middle) of <span>A(-1, 4) and B(7, 6).
Lets graph these following coordinates.

The length of missing sides x = 5 units and y = 5 units.
<h3>What is Trigonometric ratios?</h3><h3>The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).</h3>
In ΔABC,
AB (Base) = y , BC(Hypotenuse) = , CA (perpendicular) = x
and ∠ABC =
Now,
tan = perp. / base
1 = x /y
x= y .................(i)
again,
sin = perp. / Hypo.
x = 5
put in equation (i), we get
y = 5
Thus, the length of missing side of the given triangle is x = 5 units and y = 5 units.
