Answer:
A
Step-by-step explanation:
In the figure shown, ABC is a right triangle with side lengths a, b, and c, and CD is an altitude to side AB. This altitude divides the triangle into two right triangles ADC and BDC. In these triangles,
So,
1. From the similarity 
you have
2. From the similarity 
you have
Hence, option A is true
Answer:
40 apples
Step-by-step explanation:
4/7 of 70
1. rewrite in mathematical terms
4/7 * 70
2. solve
4/7 * 70
= 40
(0,2) and (1,1)
slope = (2 - 1)/(0 -1) = -1
y intercept b = 2
equation
y = -x + 2
answer
equation
y = -x + 2
Answer:
True
(1) You can prove two triangles are similar using AA similarity.
(2)If side length of similar figure have ration 
then the ratio of surface areas will be:
(3)If side length of similar figure have ratio of 
then perimeter will have ratio:.
False:
(1)If side length of similar figure have ration then the ratio of Volumes will be:
(2)If side length of similar figure have ration then the ratio of surface area will be:
Answer: B
Step-by-step explanation:
∠a and ∠b are complementary angles. Complementary angles are two angles adjacent to each other that add up to 90°. We know this is true because of the 90° angle that is labelled.
Vertical angles are not adjacent to each other. They are across from each other, connected by the angle. They are equal in angles. It is clear that ∠a and ∠b are not equal in angles. Therefore, they are complementary angles.
