Math helps with science because you'll need to know the math in order to convert units in science.
The fraction 5/7 to a decimal is: 0.71428571
Answer:
x = 4
Therefore, for the triangles to be congruent by HL, the value of x must be 4.
Step-by-step explanation:
Given: ΔABC and ΔHGL are congruent. ∠ABC = ∠HGL = 90°.
Length of hypotenuse AC = 15
Length of hypotenuse HL = 3x + 3
Length of AB = 9, Length of BC = 12 and Length of GL = 2x + 1.
Sol: ∵ ΔABC ≅ ΔHGL
Length of HL = Length of AC (corresponding parts of congruent triangles)
3x + 3 = 15
3x = 15 - 3
3x = 12
x = 12/3 = 4
Therefore, for the triangles to be congruent by HL, the value of x must be 4.
Answer:
3 hours
Step-by-step explanation:
t = time to make a table
c = time to make a chair
t + c = 5
t+3c = 9
Subtract the second equation from the first
t+3c = 9
-(t + c = 5)
-----------------------
2c = 4
Divide by 2
2c/2 = 4/2
c =2
2 hours for the chair
t+c = 5
t+2 = 5
t = 5-2
t = 3hours
