Answer:
x ≈ 49.7°
Step-by-step explanation:
Since, the given triangle is an isosceles triangle,
Two sides having measure 17 units are equal.
Opposite angles of these equal sides will be equal.
Measure of the third angle = 180° - (x + x)°
By sine rule,

[Since, sin(180 - θ) = sinθ]



cos(x) = 
x = 49.68°
x ≈ 49.7°
Answer:
8
Step-by-step explanation:
Step 1:
0.5x - 3 = 2 - 0.75x Equation
Step 2:
1.25x - 3 = 2 Add 0.75x on both sides
Step 3:
1.25x = 5 Add 3 on both sides
Step 4:
5 ÷ 1.25 Divide
Step 5:
x = 4 Solution to x
Step 6:
2 × 4 Multiply to find answer of 2x
Answer:
2x = 8
