Answer:
Step-by-step explanation:
<u>Given expressions:</u>
- 8 = x - 2 ⇒ x = 8 + 2= 10
- 3 = x ÷ 4 ⇒ x = 3*4 = 12
- x - 6 = 5 ⇒ x = 5 + 6 = 11
- x - 3 = 9 ⇒ x = 9 + 3 = 12
3 of them involves addition, one of them - multiplication
The second expression doesn't belong
Answer:
It should be congruent by the AAS congruence theorem
Step-by-step explanation:
The error is in the congruence theorem.
We know that the 2 angles are congruent and one of the sides are congruent. This means that it can either be congruent by ASA or AAS.
It is actually congruent by AAS because it include two angles and the side is opposite of one of the angles.

Step-by-step explanation:
Where were u these days
(1) 12, (2) 5, (3) 13, (4) 30
Step-by-step explanation:
(1) Given expression 2x.
Substitute x = 6 in expression 2x.
⇒ 2 × 6 = 12
(2) Given expression 8 + 3 – x
Substitute x = 6 in expression 8 + 3 – x.
⇒ 8 + 3 – 6 = 11 – 6 = 5
(3) Given expression 6 + 7 – 6 + x
Substitute x = 6 in expression 6 + 7 – 6 + x.
⇒ 6 + 7 – 6 + x = 6 + 7 – 6 + 6 = 13
(4) Given expression 5x
Substitute x = 6 in expression 5x.
⇒ 5× 6 = 30
<h3>Given:</h3>
angle CED = 45°
angle EDC = x
angle DCE = 2x
<h3>To Find:</h3>
The value of x.
<h3>Angle Sum Property:</h3>
The sum of all the Interior Angles of a triangle is 180°.
<h3>Solution:</h3>
x + 2x + 45° = 180°
or, 3x = 180° - 45°
or, 3x = 135°
or, x = 135/3 = 45°
<h2>Answer:</h2>
The value of x is 45°.
