Answer: The final answer to this question is 4:3
Step-by-step explanation:
The definition of a ratio is "the quantitative relation between two amounts showing the number of times one value contains or is contained within the other." In English, it's essentially how many "things" there are for every "other thing" there is. In this case, for every 8 girls there are, there are also 6 boys. There are many ways to write a ratio but the main one is with a colon.
So the ratio would be written like this 8:6
However, the statement requires it to be in simplest form so we need to simplify the ratio. We do that much like simplifying a fraction. Find the least common denominator, then divide both values by it. In this case the LCD is 2. So all we need to do now, is divide both the numbers in half, then we have our simplified ratio.
See :
8/2 = 4
6/2 = 3
So our new and final ratio is 4:3
Hope this helped you understand :)
Answer:
Step-by-step explanation:
Since, CD is an altitude, ∠CDB will be a right angle.
m∠CDB = m∠CDA = 90°
By applying triangle sum theorem in ΔABC,
m∠CAB + m∠CBA + m∠ACB = 180°
20° + m∠CBA + 90° = 180°
m∠CBA = 180° - 110°
= 70°
Therefore, m∠CBD = 70°
By applying triangle sum theorem in ΔBCD,
m∠BCD + m∠CDB + m∠DBC = 180°
m∠BCD + 90° + 70° = 180°
m∠BCD + 160° = 180°
m∠BCD = 20°
m∠CAD = m∠A = 20°
m∠ACD = 90° - m∠BCD
= 90° - 20°
m∠ACD = 70°
