Answer:
3√2
Step-by-step explanation:
Given the following;
DB = 3
CD = 6,
Required
find AD.
using the similarity property of a triangle
DB/AD = AD/CD
3/AD = AD/6
3*6 = AD²
18 = AD²
AD = √18
AD= √9*√2
AD = 3√2
Hence the measure of AD is 3√2
I'm pretty sure this is D, but I'm not completely positive.
The width is x
<span>The length is x+60 </span>
<span>so x(x+60) = 16000
</span>
<span>x^2 + 60x = 16000
</span>
<span> </span>
<span>x^2 + 60x + 900 = 900+16000
</span>
<span>(x+30)^2 = 16900
</span><span> </span>
<span>x+30 = 130
</span>
<span>x = 100
So your answer is 100. </span>
X - 3 < -11
x < -11 + 3
x < - 8
x + 5 > = 14
x > = 14 - 5
x > = 9
open circle on -8, shading to the left.....closed circle on 9, shading to the right
Answer:
y = 90°
Step-by-step explanation:
- 110° is the measure of exterior angle of bigger triangle.
- -> (x + x) + 70° = 110° (By exterior angle theorem)
- y is the measure of exterior angle of smaller triangle.
- -> y = x + 70° (By exterior angle theorem)
