➷ As you can tell, the ratio of the lengths is 2 : 1 (the length of a is twice the length of b)
The ratio for area would be the squared version of the length ratio
2^2 = 4
1^1 = 1
The ratio for area is 4 : 1

The question is first asking us to multiply 28x2, which equals 56. We're going to then round 56 to the nearest ten. The six is greater than five, so we round up,many we're going to round up to 60. So, 60 is your answer.
Answer:
6
Step-by-step explanation:
As the highest power of x in the expression is 6, the degree is 6
Answer:
In any instance.
Step-by-step explanation:
A triangle has three sides, and the angle measures for all three angles will add up to a total of 180°.
∠A + ∠B + ∠C = 180°
<u><em>Example:</em></u>
Find ∠C if ∠A = 60° and ∠B = 50°.
60° + 50° +∠C = 180°
∠C = 70°
Find the length of AB
AB²=20²+15²
AB²=400+225
AB²=625
AB=25
then find AD and BD
20²=AD·25
400=AD·25
AD=16
15²=BD·25
225=BD·25
BD=9
now use the geometric mean theorem (name?) to find CD
CD=√(9·16)
CD=√144
CD=12 cm
