Answer:
volume of the triangular prism = 105cm³
Step-by-step explanation:
to find the volume of a triangular prism , given the three sides to be 3cm, 10cm, 7cm,
so, recall the formulae for calculating the volume of a triangular prisim
volume of the triangular prism = 1/2 x a x b x c
volume of the triangular prism = 1/2 x 3cm x 10cm x 7cm
volume of the triangular prism = 3cm x 5cm x 7cm
volume of the triangular prism = 105cm³
therefore the volume of the trangular prism is evaluated to be equals to 105cm³
Answer:
18.56
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
5 : 6 = Number of boys to girls
(We have to ×2 to get from 5 to 10 so we must ×2 from 6 to 12)
10 : ? = Number of Boys to girls
10 : 12 = Number of Boys to girls
Answer:
Option A 90,68
Step-by-step explanation:
see the attached figure to better understand the problem
The figure shows a kite
we know that
A kite properties include
1) two pairs of consecutive, congruent sides
2) congruent non-vertex angles
3) perpendicular diagonals
Find the measure of angle 1
we have that
----> by the diagonals are perpendicular
Find the measure of angle 2
we know that
triangle AEB is congruent with triangle CEB
so
In the right triangle EAB
----> by complementary angles in a right triangle
so
therefore
