6 5/6 ounces
(concert 4.5 into a fraction, then add)
Having that 30 boys is 40% of students.
30 is 40% of students the how many students is 100%. Naming X number total of students.
X=(30*100)/40=75. Then having that there are 30 boys, numbers of girls is 75-30=45.
Answer/Step-by-step explanation:
✔️Find BC:
Reference angle = 50°
Opposite = BC
Adjacent = 5 cm
Based on trigonometric ratio, thus:
Tan 50 = BC/5
Multiply both sides by 5
BC = 5 × tan 50
BC = 5.96 cm (to 3 s.f)
✔️Find x:
Reference angle = 38°
Opp = x
Adj = BC = 5.96 cm
Based in trigonometric ratio, thus:
Tan 38 = x/5.96
Multiply both sides by 5.96
x = 5.96 × tan 38
X = 4.66 (3 s.f)
Recall that the sum of all interior angles in a triangle is 180°, and that a flat-line is always 180°.
