Answer:
In a right triangle the biggest angle is 90°.
Then the two smaller angles sum up 180° - 90° = 90 °.
Now you can use this equation: 3x + 6 + 2x - 1 = 90 and solve for x:
5 x + 5 = 90
5x = 85
x = 85/5
x = 17
Then, the smallest angle is 2(17) - 1 = 33°

<span>The correct answer is YES.
Perch and chimps they share a common ancestor.
A common ancestor is species that multiple species do share a species. Many years ago, ancestors began to diverge. This diverging led to different lineages and later raised to different species.
For example, human and apes evolved from a common ancestor. Humans and yeast they share the same common ancestor in that human have genes that codes for myosin, and also a gene in yeast which too codes for myosin protein.</span>
