<span>Complementary angles by definition sum up to 90 degrees.
Let x = measure of angle2.
It's given that angle1 = x + 54
Since complementary, we know (x+54)+x = 90
2x+54=90
2x=36
x=18.
So angle2 measures 18 degrees and angle1 is 18 degrees+54 degrees, or 72 degrees. 72+18 = 90 as expected for complementary angles.</span>
Answer:
If you have written the sides of both triangles in the same order , The congruent side will be ED . Else it could be anything . It would be more better if you could put a figure
Let x = width
x+1 is then the length
2x+2(x+1)=66
2x+2x+2=66
4x=64
x=16
deck will be 16x17, nice for a BBQ. :)
Answer:
?= 3
Step-by-step explanation:
let x = ？
18-2x=4x
6x=18x
x=3
Answer:
y=4
Step-by-step explanation:
4y + 3 =19
4y = 16
y= 4
