Answer:
its
Step-by-step explanation:
look at the row and times it by 6x5= 30
The largest triangle and the triangle whose hypotenuse is x are similar. So:
(21 + 4)/x = x/4
Cross multiply:
x^2 = 100
x = 10
Your answer is incorrect. It should be 10, not 20.
The triangle must be isosceles. because they have 2 same angles. The two sides of the triangle has to be congruent. 3×5=15, 10+5=15
15=15. the answer would be C.
Exercise 1:
The angle in the low left corner is supplementar with the external angle. Since the external angle is 105, the inner angle is 75.
Since in every triangle the inner angles sum to 180, we have

Exercise 2:
Again, you need to use the fact that in every triangle, the sum on the inner angles is always 180.
Exercise 3:
Since PQ and BC are parallel, triangles APQ e ABC are similar. This means that their side are in the same proportion, so

Plug the known values of AB, AP and AC and solve for AQ:

Answer:
V = 54 pi in ^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
V = pi (3)^2 * 6
V = pi (9) *6
V = 54 pi in ^3
