Using pythagorean theorem, you can find the hypothesis of one triangle.
2^2+b^2=4^2
4+b^2=16
b^2=14
take the square root and you would get b=3.7
After, you would do the same thing, except use 3 for A.
3^2+x^2=3.7^2
9+x^2=13.69
x^2=4.96
take the square root and get x=2.2
Answer:
x=0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5x+2=9x−14x+7−5
5x+2=9x+−14x+7+−5
5x+2=(9x+−14x)+(7+−5)(Combine Like Terms)
5x+2=−5x+2
5x+2=−5x+2
Step 2: Add 5x to both sides.
5x+2+5x=−5x+2+5x
10x+2=2
Step 3: Subtract 2 from both sides.
10x+2−2=2−2
10x=0
Step 4: Divide both sides by 10.
10x/10 = 0/10
Answer:
x=0
10 less than 5 times the value of a number -> 5a - 10
10 times the quantity of 12 more than one-fourth of a number -> 10(12+1/4a)
We have :
5a - 10 = 10(12 + 1/4a)
5a - 10 - [10(12 + 1/4a)] = 0
5a - 10 - (120 + 5/2a) = 0
5a -10 - 120 - 5/2a = 0
Group : (5a-5/2a) - (10 + 120) = 0
5/2a - 130 = 0
5/2a = 130 -> a = 130 : 5/2 = 52
Recheck : 5 x 52 - 10 = 250
10 x (12 + 1/4 x 52) = 10 x (12 + 13) = 10 x 25 = 250
