Answer:
66.4°
Step-by-step explanation:
To find the angle XYZ, we are to use sine rule. For this, we have to first find ∠Z.
Given that: ∠X = 90° (right angle), XY = 6 cm, YZ = 15 cm. Hence:
∠X + ∠Y + ∠Z = 180° (sum of angles in a triangle)
90 + ∠Y + 23.6 = 180
113.6 + ∠Y = 180
∠Y = 180 - 113.6
∠Y = 66.4°
∠Y = ∠XYZ = 66.4°
Step-by-step explanation:
2.5 m = 250 cm
so, the scale factor is 1/250
that means the tennis court is in reality
10×250cm × 5.5×250cm = 2500 × 1375 = 3,437,500 cm²
1 m² = 100×100 = 10,000 cm²
so,
3,437,500 cm² = 343.75 m²
Answer:
x = i√3, -i√3
Step-by-step explanation:
Simply take the root of both sides, then solve.
Answer:
450 minutes
Step-by-step explanation:
15 + 0.1x = 60
15 - 15 + 0.1x = 60 - 15
0.1x = 45
x = 450
