Answer:
Figure 1
Step-by-step explanation:
Congruent shapes are shapes that share the same side lengths and angle measures. In figure 1, we see that all sides and angles are marked equal, thus both shapes are congruent. However, in figure 2, we clearly see that the sides of each of the triangles are different. Thus, the triangles in figure 2 are not congruent.
Answer:
1) $3.82 2) $21.68
Step-by-step explanation:
If it's 15% off, the price is 85% of the original price---
, and this gives a difference from the original price and the new price of
.
66/128 * 100
51.56 % if rounding to the nearest hundredth.
51.6 % if rounding to the nearest tenth.
52 % if rounding to the nearest whole number.
I have attached the work for your first problem.
Check the picture below.
notice, in a right-triangle, there is a right-angle, thus is called a right-triangle, and the other angles are complementary angles.
notice the relation of the cosine and sine of each, in the example in the picture.
