4. Which equation could be used to find the value
of x in the triangle below?
4x
+ 101
2x
6x - 10
A. 12x + 20 = 180
B. 12x = 180
C. 12x – 20 = 180
10.) 8x – 10 = 4x + 10

△cde maps to △stu with the transformations (x, y) arrowright (x − 2, y − 2) arrowright (3x, 3y) arrowright (x, −y). if cd = a + 1, de = 2a − 1, st = 2b + 3 and tu = b + 6, find the values of a and b. the value of a is and the value of b is .

Assume that a population of 50 individuals has the following numbers of genotypes for a gene with two alleles, b and b: bb = 30, bb = 10, and bb = 10. calculate the frequencies of the two alleles in the population’s gene pool.

He that is measured at 220° is a reflex angle. the opposite angle is obtuse. find the measure of obtuse .
