<h3>
Answer: 20 square units (choice C)</h3>
============================================================
Explanation:
Ignore the portions that are 12 and 13 units long.
The base of triangle ABC is 8 units long. The height is 5 units. The base and height are always perpendicular.
The area is base*height/2 = 8*5/2 = 40/2 = 20 square units

Side note:
You could find the area of triangle ABD, where D is at the 90 degree angle location, and then subtract off the area of triangle ACD. This is a slightly longer approach compared to the first section above.
Answer:
109
Step-by-step explanation:
alternate exterior angles
Answer:
Step-by-step explanation:
- 3 = + 2x ...... <em>(1)</em>
(1) × 12 :
3x - 36 = 4 + 24x
21x = - 40
x = - =
7/3.5
multiply and divide by 10
= 7×10/3.5×10
= 70/35
= 14/7
=2
The answer is 2
