In triangle ABC, D is the midpoint of side AC and E is the midpoint of side BC.
1 answer:
Answer:
14
Step-by-step explanation:
Since all sides are half of greater triangle.Then 7 × 2 = 14 is length of greater hypotenuse.
Suppose two triangles with similar conditions
1^2+1^2=2
Hypotenuse=2^1/2
We assume another triangle which is exactly double of previous triangle I.e
2^2+2^2=8
Hypotenuse=2×2^1/2
Which is exactly twice of previous triangle.
Hence proved hyootenuse is double of smaller triangle I.e 14

Answer:
64°
Step-by-step explanation:
We know that a right angle is 90°
so we do 90° - 26° = 64°
4.5 x 10^6 = 4,500,000
2.1 x 10^8 = 210,000,000
Therefore, 4.5 x 10^6 < 2.1 x 10^8
