Answer:
smallest triangle BCD
x = 15
Step-by-step explanation:
9/x = x/(16 + 9)
x² = 25(9)
x = ±15

Answer:
x=12
Step-by-step explanation:
To make these 2 lines perpendicular to each other, one of their angles must be equal to 90 degrees.
Therefore, we can set up an equation with one of the angles:
7x+6=90
7x=84
x=12
The information of the other angle is useless in this case, but we can use it to check by plugging in 12 for x, and seeing if it equals to 90:
8*12-6=96-6=90
Therefore, x=12.
Answer:
17.5m
Step-by-step explanation:
958.2 minus 23.9= 934.3
934.3 minus 951.8= - 17.5
the negative doesnt matter so you can take that away so the answer is 17.5
C: 14X•X=14X^2
Also fyi you can always looks these up it might be hard to find the answers but still
