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°

hi
monthly interest rate is : ![\sqrt[12]{1.05}](https://tex.z-dn.net/?f=%5Csqrt%5B12%5D%7B1.05%7D)
So in forty month there will be : 10 000 * ( )^40 ≈11 776,06
I guess it would be true because 100+95+85+80 = 360, and there are 360 degrees in a circle.
Simply cross multiply and simplify to get a = 11
Hope this helped!! xx
