Answer:
17.28in
Step-by-step explanation:
To find the area of a triangle, multiply the base by the perpendicular height (the length from the point opposite the base, to the base, which makes a 90-degree angle with the base), and half it:
7.2*4.8=34.56
34.56/2=17.28
Since angles 3 and 4 are supplementary, they add up to 180 degrees.
Angle 3 is 88 degrees.
To get the measure of the last angle, let's subtract 88 from 180.
180 - 88 = 92
Thus, Angle 4 has a measure of 92 degrees.
Have an awesome day! :)
