Double checking: On the first try I got 113, That turned out to the the wrong answer. I understand how 23 and 67 can be a answer
but 77 I can’t seem to do the math for it, so if someone can help me get the right answer, please and thanks.

Answer:
∠DCE = 67
Step-by-step explanation:
In triangle DCE,
∠DCE + 23 + 90 = 180 (angle sum property)
=> ∠DCE + 113 = 180
=> ∠DCE = 180 - 113
=> ∠DCE = 67
Hope it helps :)
Please mark my answer as the brainliest
The answer is 67°.
Step by step explanation:
Since all triangles equal 180°
Let x be the value of m∠DCE.
x + 23° + 90° = 180°
x = 180° - 90° - 23°
x = 67°

Answer:
let the width be x inches
then the length would be 3x inches
perimeter of rectangle = p = 2(l+b)
100= 2(3x+x)
100= 2(4x)
100=8x
x=100/8
x=12.5 inches
thw width is 12.5 inches and length is 3*12.5=37.5 inches
Step-by-step explanation:
Take the root of both sides, and solve.
x = 2i sqrt 2, -2i sqrt 2.
Answer:
C = 132°
Step-by-step explanation:
(5y + 28) = 12y
5y - 5y + 28 = 12y - 5y
28 = 7y
y = 4
12 (4)
= 48
48 + C = 180°
48 - 48 + C = 180 - 48
C = 132°
It will be x, if y depends on x
Because tent is dependent and the is independent
The factors of 25 and 60 would be 5. 25 divided by 5 is 5 and 60 divided by 5 is 12.
So here is what the distributive property looks like.
a(b+c)=a*b+a*c but we are going to rewrite a*b and a*c as 5*5 and 12* 5
a(b+c)=5*5+12*5
So i'd say its 5*5+5*12 i hope this helps
