Step-by-step explanation:
Ratio = 4 :3
Other two sides = 4x , 3x
Pythagorean theorem
(4x)² + (3x)² = 20²
16x² + 9x² = 400
25x² = 400
x² = 400 ÷ 25
x² = 16
x = √16
x = 4 cm
4x = 4*4 = 16
3x = 3*4 = 12
Sides = 16cm , 12 cm
Answer: infinitely many solutions
Step 1)
√25y² +16 =5y + 4
(√25y² + 40y + 16)² = (5y + 4)²
25y² + 40y + 16 = (5y + 4)²
25y² + 40y + 16 = (5y)² + 2 × 5y × 4 + 4²
25y² + 40y + 16 = 5² × y² + 2 × 5y × 4 + 4²
25y² + 40y + 16 = 25y² + 2 × 5y × 4 + 16
25y² + 40y + 16 = 25y² + 40y + 16
25y² + 40y + 16 = 25y² + 40y + 16
25y² + 40y + 16 − 25y² − 40y − 16 = 0
0 = 0
A right triangle means that one angle is 90 degrees. If the other is 30 then we can figure out the last one.
A triangle’s interior angles add up to 180 so all we have to do is subtract the other angles from 180 to find the remaining one.
180-90-30=60.
The third angle is 60 degrees.
20s-13s=-10-4 sooo 7s=-14 so divided both sides by 7 sooo s=-2
