2x + 1.5x +20 = 90
3.5 x = 90-20
3.5 x = 70
x = 70/3.5
x = 20
angle DAE = 2*20 = 40
angle CAD = 1.5*20 +20 = 50
Answer:
139
Step-by-step explanation:
if one side is 139 the other side is 139
38
How do we check the result?
If 50% × 38 = 19 =>
Divide 19 by 38...
... And see if we get as a result: 50%

Cos 45 = √6 / y
√2 / 2 = √6 / y
Inverse both sides
2 / √2 = y / √6
Multiply both sides by √6
√6 × 2 / √2 = √6 × y / √6
√2 × √3 × 2 / √2 × 1 = y
<h2>y = 2√3</h2>
