Answer:
92in^2
Step-by-step explanation:
Find the length of the bottom right triangle.
Use Pythgoras theorem
You will get 8
(1/2)(6)(2)(2)= 12
12+(10)(8)=92
1/4 = 0.25
8.25 + 0.25w = 10.25
0.25w = 10.25 - 8.25
0.25w = 2
w = 2 / 0.25
w = 8 <===
Answer:
domain {-1,1.3}
Step-by-step explanation:
The domain is the input values, or in this case the first or x values
domain {3,1,-1,-1}
We do not put the same value twice
domain {3,1,-1}
We like to put them in numerical order
domain {-1,1.3}
Answer: AA similarity theorem.
Step-by-step explanation:
Given : AB ∥ DE
Prove: ΔACB ≈ ΔDCE
We are given AB ∥ DE. Because the lines are parallel and segment CB crosses both lines, we can consider segment CB a transversal of the parallel lines. Angles CED and CBA are corresponding angles of transversal CB and are therefore congruent, so ∠CED ≅ ∠CBA.
Also ∠C ≅ ∠C using the reflexive property.
Therefore by AA similarity theorem , ΔACB ≈ ΔDCE
- AA similarity theorem says that if in two triangles the two pairs of corresponding angles are congruent then the triangles are similar .
