The isosceles triangle has two sides congruent which mean they are equal. If two sides are equal, it also means that two angles are equal.
For triangle XYZ, we have angles shown below:
∠X + ∠Y + ∠Z = 180°
If ∠Y = a°, then we can have the expression for ∠X such as shown below:
∠X + a° + ∠Z =180°
∠X= 180° - a° - ∠Z
If ∠Z = ∠Y, then we have the final expression:
∠X = 180° -2a°
3/x=36
Multiply both sides by x
3=36x
Then divide both sides by 36
3/36=x
1/12=x
Final answer: 1/12

Question 23
Lateral Surface Area = πD x height
Lateral Surface Area = π (4) (6) = 75.40 in²
Question 24
Total Surface Area = 2(8.2 x 3.4) + 2(8.2 x 2) + 2(3.4 x 2)
Total Surface Area = 36.56 in²
Question 25
Total Surface Area = 2(10 x 12) + 2(12 x 4) + 2(10 x 4)
Total Surface Area = 416 in²
