Using Pythagoras Theorem,

(12)^2+ (a)^2= (13)^2

144+a^2= 169

a^2= 169-144

a^2= 25

a= √25

a= 5mm

Hope it helps you.

Answer:

105/24

Step-by-step explanation:

The volume of a rectangular prism is length*width*height.

3/2 * 5/4 * 7/3 would be 15/8*7/3 which is 105/24, which is the fourth option.

Answer:

20in²

Step-by-step explanation:

The area of a triangle is calculated using the formula A = bh/2

"A" means area.

"b" is for the base.

"h" is for the height.

It does not matter which is the base and which is the height, as long as they are perpendicular (at 90°) to each other.

5in can be the height.

8in can be the base.

Put the base and height measurements into the formula.

A = bh/2

A = (8in)(5in)/2    Multiply the measurements and the units.

A = (40in²)/2   Divide by 2

A = 20in²       Area of the triangle

When you multiply units, in X in becomes in².

"in" has the exponents 1. When you multiply two "in" with exponent 1, you add the exponents. 1 + 2 = 2.

in¹ X in¹ = in¹⁺¹ = in²
