The area of a triangle is 10 square cm. The base is LaTeX: 2\:\frac{1}{2}2 1 2 cm. Find the height.

Step-by-step explanation:

Given

Shape: Triangle

Required

Determine the height

Area of a triangle is calculated as:

Substitute values for Area and Base

Multiply both sides by 4

Hence, the height is 40cm

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
