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°

[11 +{-18 divided by 9}]x2<br><br> HELP! Please and thanks
USPshnik [31]

Answer:

7 is the answer.

Step-by-step explanation:

In equations like this, you would solve the numbers in the parenthesis first, and then gradually do: Multiplication -> Division -> addition -> subtraction.

Therefore, -18 / 9 is -2.

-2 * 2 would be -4,

11 + (-4) would be 7.

Answer : 7.
