The Volume of triangular prism
V = 450 cm³
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given The area of cross section of a prism A = 45cm²
and height (h) = 10 cm
The Volume of triangular prism
V = ( Base area X Height )
= 45 X 10
= 450 cm³
The Volume of triangular prism
V = 450 cm³
R = {10; 15; 20}
S = {20; 25}
R U S = {10;15; 20; 25;
Answer:The flag of a country contains an isosceles triangle (recall that an isosceles triangle contains two angles with the same measure) if the measure of the third angle of the triangle is 20 degrees more than twice the measure of either of the other two angles and find the measure of each angle of the triangle (Recall that the sum of the measures of the angles of a triangle is 180 degrees)
