Answer:
12.3 = y
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj/ hyp
cos 35 = y/15
15 cos 35 = y
12.28728066 = y
To the nearest tenth
12.3 = y
Answer:
1) E and F
Step-by-step explanation:
So width is x
legth Is 3x+3
Perimeter is
3x+3+3x+3+x+x
Now simplify
8x+6
Now go through each choice that equals 8x+6
Only e and f
Answer:
whats the list
Step-by-step explanation:
Opposite angles are supplementary, the sum is 180 degrees.
6x+10+81.5=180
Combine like terms:
6x+91.5=180
Subtract 91.5 to both sides:
6x=88.5
Divide 6 to both sides:
x=14.75
The answer is 1) 14.75
Hope this helped!
