Angle EGD = x (vert. opp. angles)
30 ° + 90 ° + x = 180 ° (adj. angles on st. line)
x = 60
Answer:
6.7cm, 13.4cm, 15cm.
Step-by-step explanation:
Let x be one side of the triangle. The question tells us the other side is 2x.
We can relate all 3 sides using the Pythagorean Theorem:

That means the side lengths are 6.7cm and 2 x 6.7 cm = 13.4cm.
6+2x; x=5
6+2(5)
6+10
16
This is the correct answer.
Answer:
<u>2 : 4 : 1</u>
Step-by-step explanation:
First take common factors by factorization.
56 = 14 x 4 = 28 x 2
112 = 14 x 8 = 28 x 4
28 = 14 x 2 = 28 x 1
Remove the 28 common factor.
Therefore,
56 : 112 : 28
= <u>2 : 4 : 1</u>
