Angles in a triangle add up to 180 degrees.
180 - 125 = 55
Add the ratios 4+7 = 11
Divide the left over angels by the ratio: 55/11 = 5
Now multiply 5 by each side of the ratio:
4:7
4*5 = 20
7*5 = 35
So the 2 angles are 20 and 35 degrees.
To check, you can add up all the angels : 20 + 35 + 125 = 180
So we know 20 and 35 is correct because it adds up to 180 degrees :)
B = 0.4
b = 0.6
Explanation:
From the question we derive that;
BB = 16%
Bb = 24%
The gene frequency for BB = 16/100 = 0.16
To find allelic frequency of B;
B = √0.16 = 0.4
Remember Hardy Weinberg rule that all allelic frequencies of a gene must sum up to 1;
p + q = 1
If p = 0.4
q = 1 – 0.4 = 0.6
b = 0.6

The correct answer is - In most Latin American countries, the majority of locals speak Spanish.
Most of the countries in South America have Spanish as their official language, but it is not just the language that is a trait that connects people, it is also the influence of the Spanish culture as well, even in the few countries where it is not a dominant language.
