Irrational because it’s negative.
Answer: 72 cm²
Step-by-step explanation: 1/2(base)(height) is the formula to find the area of a triangle. To find the area of the bigger triangle we substitute 10 cm for the base and 6 cm for the height.
1/2(10)(6)
1/2(60)
30 cm²
since we have two of the same triangles, we double that
we also have a smaller triangle. 14-10=4 which is the base of the smaller triangle.
1/2(4)(6)
1/2(24)
12 cm²
now, we add everything
60 cm² + 12 cm² = 72 cm²
Just write down any random equation and you will be correct.
1 is 100 degrees
2 is 72 degrees
3 is 9 degrees
4 is 125 degrees
5 is 155 degrees
6 is 91 degrees
7 is x=28 degrees
8 is x=125 degrees
9 is x=35
10. angle 2 is 86 degrees (vertical angles)
11. angle 3 s 94 degrees (supplementary to angle 2)
12. angle 4 is 86 degrees (<4 and <2 are alt. interior angles and are congruent)
13. angle 6 is 86 degrees (<6 and <4 are vertical angles)
