Answer:
6 square inches
Step-by-step explanation:
The formula for area of a triangle is:
1/2(b*h)
Therfore;
b=4, h=3
So,
1/2(4*3)
1/2(12)
=1/2 * 12
= 6 square inches

Using the percentage concept, it is found that 40% of Alberto’s income is used to pay for his rent and groceries.
<h3>What is a percentage?</h3>
The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

This can be expanded through the tangent angle addition formula:
tan(α+β)=tanα+tanβ1−tan -α + tanβ
Thus,tan(x+y)=tanx+tany1−tan x tany
