Haha what? Is this like a joke..how does a cat have 18 legs.what that’s confusing
Answer:
a) <u>∡ADC = 270°</u>
b) <u>∠DAE = 38°</u>
Step-by-step explanation:
Using Inscribed Angle Theorem :
- ∡ADC = 2 x ∠ABC
- ∡ADC = 2 x 135°
- <u>∡ADC = 270°</u>
Similarly :
- ∠DAE = 1/2 x ∡DE
- ∠DAE = 1/2 x 76°
- <u>∠DAE = 38°</u>
A Pythagorean theorem question is one that deals with the side lengths of a RIGHT triangle.
When solving a question you would use the formula, a^2 + b^2=c^2
A and B are both of the sides that aren’t the hypotenuse.
C is distinguishable from a and b as it is the side opposite from the 90 degree angle. (90 degree angles are formed by perpendicular lines)
