Step-by-step explanation:
Since we have a right triangle, we use the Pythagorean Theorem
or
where a and b are the legs and c is the hypotenuse
Remember the legs are the sides that form that right angle, and the hypotenuse is the side opposite of the right angle.
So here the hypotenuse is 8, and one of the legs is 4. So we plug those values into the formula
Answer:
A
Step-by-step explanation:
First, you take base*base*height. Therefore;
A= a+b/2h
= 1.9+3.7/2 * 0.9 = 2.52
Hope this helped!
Add E on AB where ED is perpendicular to AB , since the distance between D and AB is 5 in , so ED is 5 in (because the distance between a point and a line is the length of the perpendicular line drawn from the point to the line)
now we have a right angled triangle AED at E , sin(DAE) = DE/AD = 5/10 =1/2
so angle DAE is 30 degrees and since angle CAB is 60 degrees
therefore AD is angle bisector of angle A
ASSUMING THE UNKNOWN IS THE HYPOTENUSE
Area=1/2absinx
Area=1/2(8)(12)sin65
Area=39.7cm^2
7/9 because you divide by the common multiplier 3
