Answer:
47 degrees
Step-by-step explanation:
total degrees in a triangle is 180
since this is a right triangle there is a 90 degree in there and it also gives the 43 degree
subtract 90 and 43 from 180 and you get 47

Answer: a=36; b=18
Step-by-step explanation:
1. You know that the sum of two numbers is 54, then, you have:
a+b=54
2. According to the problem, the larger number is 18 more than the sampler number, this can be expressed as following:
a=b+18
3. Then, you must substitute the second equation into the first equation and solve for b:
b+18+b=54
b=18
4. Then the value of a is:
a+18=55
a=36
Answer:
-10
Step-by-step explanation:
Recombinant frequency between T and A is 12%
<u>Explanation:</u>
<u></u>
Two characters are considered - height and antennae
Traits of height - Tall and Dwarf
Traits of antennae - Antennae and No antennae
<u>Given:</u>
<u />
Tall-antennae (46) and dwarf-no antennae (42) are the wild type.
Dwarf- antennae (7) and tall- no antennae (5) are the recombinants.
Total possibilities = 100
Recombinant frequency = 
Recombinant frequency = 
Recombinant frequency in percentage =
%
Therefore, recombinant frequency between T and A is 12%
