Complementary angles add up to 90°
∠BDC + ∠CDA = 90°
Answer: ∠BDC
Answer:
Step-by-step explanation:
The last three are irrational but I'm not sure about the first four.
A line has the angle of 180°
I'm going to assume that blurry number is a 35, but you can use this for any situation
180 - 35 = 145°
Angle x and y are the same
12.072 is irrational because it cannot be simplified into a fraction or ratio.
Answer: First option is correct.
Step-by-step explanation:
Since we have given that

Now, by factorising , we get

Now, we use the formula i.e.

By using this, we get ,

So,
