Answer: 23 is your answer
Step-by-step explanation:
Answer/Step-by-step explanation:
Problem 1:
Reference angle = 36°
Opposite = x
Adjacent = 7
Thus, apply trigonometric ratio as follows:
tan 36 = x/7
Multiply both sides by 7
7 × tan 36 = x
x = 5.09 (nearest hundredth)
Problem 2:
Reference angle = 63°
Opposite = 12
Hypotenuse = x
Thus, apply trigonometric ratio as follows:
Sin 63 = 12/x
Make x the subject of the formula
x = 12/sin 63
x = 13.47 (nearest hundredth)
The first statement is correct. Congruent angles have the same angles.
Answer:
a) 16.5 inches
b) 1.64 radian
c) 22.3feet
Step-by-step explanation:
a) r = 3in
θ = 5.5rad
s = 3 × 5.5
= 16.5in
b) s = 6.4in
r = 3.9in
6.4 = 3.9 × θ
θ = 1.64rad (3sf)
c) θ = 126°
arc = 49ft
49 = (126÷360)×2×3.142×r
r = 49 ÷ 2.1994
= 22.3ft (3sf)
