Pretty much just look at the congruent symbols and you can figure it out.
1800 because the 18 cant fit in the tens
Answer: 48
Step-by-step explanation: COB and DOA are vertical angles. This means the two of them have the same measure. Because we know the measuremen of DOA, we can easily find the measuremen for COB since these angles are the same, so COB is 48 degrees.
Answer:
27.5cm^2
Step-by-step explanation:
you can cut the triangle to make two right triangles
so 11 is the height and the width is 2.5 since your cutting the triangle in half
so 11x2.5=27.5 since its a right triangle you have to divide by two 27.5/2=13.75
that's the answer for one of the triangles now multiply it by two since you need the two right triangle to make the other triangle so the answer is 27.5
