I cant see the picture good can you write it out not in picture because it is blury for me I dont know about the others
⁻⁻Using Sine ratio: opposite / Hypotenuse
Opposite to angle A = 24, Hypotenuse = 25
Sin A = 24 / 25
Sin A = 0.96
A = Sin⁻¹(0.96) Use a calculator.
A ≈73.74°
A ≈ 73.7°
∠A + ∠B = 90° Since it is a right angled triangle.
∠B = 90° - ∠A
∠B = 90° - 73.7°
∠B = 16.3°
Answer:
(c.) m∠A ≈ 73.7°, m∠B ≈ 16.3°, m∠C = 90°
Answer:
42
Step-by-step explanation:
the 2 part of the ratio refers to 14 girls , then
14 ÷ 2 = 7 ← value of 1 part of the ratio , so
4 parts = 4 × 7 = 28 ← number of boys
total members = 14 + 28 = 42
Answer:
B. 22 cm
Step-by-step explanation:
Perimeter of a parallelogram is 2(l+w)
= 2(8+3)
=2(11)
=22cm
