If you do 138 divided by 12 you get 11.5, but since you can't have 11.5 full tables you know that there are only 11 full tables .
Answer:
X= 67
Y= 121
Z= 80
Step-by-step explanation:
To find Y:
(y-9) and 112 are congruent so
y-9=112
y=121
To find Z: (consecutive)
180=121+z+3
180=124+z (combine like terms)
subtract 124 to cancel and move to other side of equation
z= 80
To find X: (consecutive)
180=112+x+1
180=113+x (combine like terms)
subtract 113 to cancel out and move to their side of equation
x = 67
You have to take the x to on side and numbers to the other but in order to do that you'll have to divide -3 from both sides and then just solve the equation.
Answer:
Step-by-step explanation:
Angle JKL is similar to angle PQR. This means that the ratio of the length of each side of ∆JKL to the length of the corresponding side of ∆ PQR is constant. Therefore,
JK/PQ = KL/QR = JL/PR
Therefore,
x/28 = 38/42
Cross multiplying, it becomes
x × 42 = 28 × 38
42x = 1064
Dividing the left hand side and the right hand side of the equation by 42, it becomes
42x/42 = 1064/42
x = 25.33 rounded up to the nearest 2 decimal places.
